Understanding Arithmetic Reasoning on the ASVAB

Overview of the Arithmetic Reasoning Section

Arithmetic Reasoning on the ASVAB measures your ability to solve word problems that require basic mathematical reasoning. It isn’t just about computation; it’s about understanding what the question is asking and determining how to apply math principles to find the solution.

The types of problems range from straightforward number operations to more complex word problems involving rates, percentages, and probabilities. Because of its real-world context, this section can be challenging if you’re not comfortable translating words into equations or identifying which operation to use.

Number Properties and Operations

Types of Numbers

A solid understanding of different number types is essential:

Whole numbers: 0, 1, 2, 3, etc. (no fractions or negatives)
Integers: … -3, -2, -1, 0, 1, 2, 3 …
Rational numbers: Numbers that can be expressed as a fraction, such as 2/3 or -4
Irrational numbers: Numbers that can’t be expressed as a fraction and have non-repeating, non-terminating decimal forms, like √2 or π

These categories often overlap; for example, every whole number is also a rational number, and every integer is also a rational number.

Operations with Integers

You must be able to add, subtract, multiply, and divide integers, including negative numbers.

Examples:

5 + (-3) = 2
-7 − 2 = -9
(-4) × 3 = -12
(-8) ÷ (-2) = 4

Watch for sign rules: a negative times a negative is a positive, but a negative times a positive is a negative.

Absolute Value

The absolute value of a number is its distance from zero on the number line. It is always positive.

Examples:

|5| = 5
|-8| = 8
|0| = 0

The absolute value is often used in distance problems or when comparing values without regard to direction.

Factors, Multiples, and Prime Numbers

Factors

A factor is a number that divides evenly into another number.

Example: Factors of 12 are 1, 2, 3, 4, 6, and 12.

To find the greatest common factor (GCF) of two numbers, list the factors of both and choose the largest one they share.

Multiples

A multiple is what you get when you multiply a number by any whole number.

Example: Multiples of 4 are 4, 8, 12, 16, 20, and so on.

The least common multiple (LCM) is the smallest number that is a multiple of two numbers.

Prime Numbers

A prime number is greater than 1 and has only two factors: 1 and itself.

Examples of prime numbers: 2, 3, 5, 7, 11, 13, 17

Understanding primes is essential for simplifying fractions and factoring.

Divisibility and Remainders

Divisibility rules help you quickly determine if one number divides evenly into another.

Common rules:

A number is divisible by 2 if it ends in an even number.
Divisible by 3 if the sum of its digits is divisible by 3.
Divisible by 5 if it ends in 0 or 5.

Remainders occur when division does not result in a whole number.

Example: 13 ÷ 4 = 3 remainder 1

Fractions and Decimals

Operations with Fractions

Addition and Subtraction: Use a common denominator.
Multiplication: Multiply the numerators together and the denominators together.
Division: Multiply the first fraction by the reciprocal of the second.

Example:

1/2 + 1/4 = 2/4 + 1/4 = 3/4
3/5 × 2/7 = 6/35
5/6 ÷ 1/2 = 5/6 × 2/1 = 10/6 = 5/3

Converting Between Fractions and Decimals

To convert a fraction to a decimal, divide the numerator by the denominator.

Example: 3/4 = 0.75

To convert a decimal to a fraction, express it as a fraction and simplify.

Example: 0.6 = 6/10 = 3/5

Comparing Fractions and Decimals

Convert both to decimals or find a common denominator to compare them.

Percentages and Applications

Percent means “per hundred.” To solve percent problems, convert between percent, decimal, and fraction forms.

50% = 0.5 = 1/2
25% = 0.25 = 1/4
75% = 0.75 = 3/4

To find a percent of a number:

Example: What is 20% of 80?
Convert 20% to a decimal (0.20), then multiply:
0.20 × 80 = 16

Percentage Increase and Decrease

These problems involve finding how much a quantity has gone up or down in percentage terms.

Formulas:

Percent Increase = [(New − Old) / Old] × 100
Percent Decrease = [(Old − New) / Old] × 100

Example: A price increases from $100 to $120.
Increase = 120 − 100 = 20
Percent Increase = (20 / 100) × 100 = 20%

Averages, Mean, Median, and Mode

Mean (Average)

To find the average, add all the numbers and divide by how many there are.

Example: Average of 4, 5, and 7 = (4 + 5 + 7) / 3 = 16 / 3 = 5.33

Median

The middle number in a sorted list.

Example: 3, 5, 7 → Median = 5
For even numbers of values, average the two middle numbers.

Mode

The number that appears most often.

Example: 2, 2, 4, 6, 6, 6 → Mode = 6

Order of Operations

The correct sequence for solving math problems is:

Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)

Often remembered as PEMDAS.

Example:
2 + 3 × (4 + 5) ÷ 3²
= 2 + 3 × 9 ÷ 9
= 2 + 3 × 1
= 2 + 3
= 5

Ratios, Proportions, and Rates

Ratios

A ratio compares two values.

Example: Ratio of girls to boys is 3:4

Proportions

Two equal ratios form a proportion. To solve, use cross multiplication.

Example: 2/3 = x/6
Cross-multiply: 2 × 6 = 3 × x → 12 = 3x → x = 4

Rates

A rate compares two different units.

Examples:

Miles per hour (mph)
Dollars per pound

Rate problems often involve speed or unit prices.

Word Problems

The ASVAB focuses heavily on applying math to real-world problems. Word problems can involve:

Time and distance
Work rate (e.g., how long two people take to complete a job together)
Discounts and taxes
Investments and interest

Key steps for solving:

Identify what the problem is asking.
Extract the relevant numbers and relationships.
Set up the correct equation or formula.
Solve and double-check your work.

Example: If a car travels 60 miles in 1.5 hours, what is the speed?
Speed = Distance ÷ Time = 60 ÷ 1.5 = 40 mph

Sequences and Patterns

Arithmetic sequences have a constant difference between terms.

Example: 3, 6, 9, 12… (common difference is 3)

Formula for the nth term:

aₙ = a₁ + (n − 1)d

Where:

aₙ is the nth term
a₁ is the first term
d is the common difference

You may be asked to identify the next term in a pattern or solve for a specific term.

Probability

Basic probability measures how likely an event is to occur:

Probability = Favorable outcomes / Total possible outcomes

Example: What is the probability of rolling a 4 on a 6-sided die?
= 1 / 6

Understand independent events (rolling a die twice) and dependent events (drawing cards without replacement).

Mathematics Knowledge – Algebra and Foundational Geometry

Introduction to Mathematics Knowledge on the ASVAB

The Mathematics Knowledge portion of the ASVAB tests your understanding of math topics that go beyond basic arithmetic. While Arithmetic Reasoning emphasizes real-world problem solving, Mathematics Knowledge focuses on more abstract and symbolic mathematics, including algebra, equations, and geometry.

This section includes many topics typically covered in Algebra I, parts of Algebra II, and Geometry. You’ll work with algebraic expressions, equations, factoring, lines, angles, and geometric formulas. A solid grasp of these topics will significantly improve your score.

Algebra Basics: Monomials, Binomials, and Expressions

Monomials and Binomials

A monomial is an algebraic expression with only one term.

Examples:

5x
3a²
-7xy

A binomial has two terms separated by a plus or minus sign.

Examples:

x + 3
4a − 2b
5x² + 2x

You’ll often be asked to add, subtract, or multiply monomials and binomials.

Combining Like Terms

Like terms have the same variables raised to the same powers.

Example:

3x + 5x = 8x
7a² − 2a² = 5a²

You cannot combine terms like 4x and 3x² because the exponents are different.

Distributive Property

Used to multiply a single term across terms inside parentheses.

Example:

3(x + 2) = 3x + 6

You may also apply the property in reverse to factor an expression:

3x + 6 = 3(x + 2)

FOIL Method and Factoring Patterns

Multiplying Binomials (FOIL)

FOIL stands for:

First
Outer
Inner
Last

It is a method to multiply two binomials.

Example:

(x + 2)(x + 3)
- First: x × x = x²
- Outer: x × 3 = 3x
- Inner: 2 × x = 2x
- Last: 2 × 3 = 6

Combine terms: x² + 5x + 6

Factoring (Unfoiling)

Factoring reverses multiplication. You’ll often factor trinomials into binomials.

Example:

x² + 5x + 6 → (x + 2)(x + 3)

You need to find two numbers that multiply to the last term (6) and add to the middle term (5).

Common factoring patterns:

Difference of squares:
- a² − b² = (a − b)(a + b)
Perfect square trinomials:
- a² + 2ab + b² = (a + b)²
- a² − 2ab + b² = (a − b)²

Solving Equations

One-Step and Two-Step Equations

One-step equation:

x + 4 = 10 → Subtract 4 → x = 6

Two-step equation:

2x − 3 = 7 → Add 3 → 2x = 10 → Divide by 2 → x = 5

The goal is always to isolate the variable.

Multi-Step Equations

These may involve distributing, combining like terms, and solving.

Example:

3(x − 2) + 4 = 19
Distribute: 3x − 6 + 4 = 19
Combine: 3x − 2 = 19
Add 2: 3x = 21
Divide: x = 7

Equations with Variables on Both Sides

Example:

5x − 2 = 3x + 6
Subtract 3x: 2x − 2 = 6
Add 2: 2x = 8
Divide: x = 4

Systems of Equations

A system of equations involves two or more equations with the same variables. You’ll usually solve for x and y.

Methods:

Substitution: Solve one equation for one variable, then substitute it into the other equation.
Elimination: Add or subtract equations to eliminate one variable.

Example:

Equation 1: x + y = 5
Equation 2: x − y = 1

Add both equations:

(x + y) + (x − y) = 5 + 1 → 2x = 6 → x = 3

Substitute x into Equation 1:

3 + y = 5 → y = 2

Answer: x = 3, y = 2

Quadratic Equations

Quadratic equations are in the form:
ax² + bx + c = 0

Common methods to solve:

Factoring (as shown earlier)
Quadratic Formula (not usually required for ASVAB)
Completing the square (also uncommon on ASVAB)

Example:

x² + 5x + 6 = 0 → (x + 2)(x + 3) = 0
Set each factor to zero: x + 2 = 0 → x = -2, x + 3 = 0 → x = -3

Inequalities

Solving inequalities is like solving equations, but with a few extra rules.

Example:

2x + 3 < 7 → Subtract 3: 2x < 4 → Divide: x < 2

If you multiply or divide both sides by a negative number, reverse the inequality.

Example:

-2x > 4 → Divide by -2 → x < -2

Graphing:

Use a number line.
Open circle for < or >, closed circle for ≤ or ≥
Shade left for less, right for greater

Geometry Basics: Lines and Angles

Types of Angles

Right angle: 90°
Acute angle: Less than 90°
Obtuse angle: More than 90° but less than 180°
Straight angle: 180°

Complementary and Supplementary Angles

Complementary: Add up to 90°
- Example: 30° + 60° = 90°
Supplementary: Add up to 180°
- Example: 110° + 70° = 180°

Vertical Angles

Formed by intersecting lines. Opposite angles are equal.

Example:
If one angle is 40°, the vertical angle is also 40°.

Parallel Lines and Transversals

When a transversal crosses parallel lines, you get:

Corresponding angles: Equal
Alternate interior angles: Equal
Same-side interior angles: Supplementary

Understanding these angle relationships is critical for solving for missing values.

Triangles

Types of Triangles

Equilateral: All sides and angles are equal (each angle is 60°)
Isosceles: Two sides (and two angles) are equal
Scalene: All sides and angles are different
Right triangle: One 90° angle

Triangle Properties

The sum of the angles in any triangle is 180°
Pythagorean Theorem (for right triangles): a² + b² = c²

Example:

a = 3, b = 4 → c² = 9 + 16 = 25 → c = 5

Quadrilaterals and Circles

Quadrilaterals

Square: 4 equal sides and 4 right angles
Rectangle: Opposite sides are equal and 4 right angles
Rhombus: 4 equal sides, angles not necessarily 90°
Parallelogram: Opposite sides are equal and parallel
Trapezoid: One pair of parallel sides

All quadrilaterals have an angle sum of 360°

Circles

Radius: Distance from center to edge
Diameter: Twice the radius
Circumference: Perimeter of a circle = 2πr or πd
Area: πr²

Coordinate Geometry

Plotting Points

Points are written as (x, y) and plotted on a coordinate plane with horizontal (x) and vertical (y) axes.

Slope and Line Equations

Slope measures steepness:

m = (y₂ − y₁) / (x₂ − x₁)

Slope-intercept form:

y = mx + b
- m is slope
- b is the y-intercept (where the line crosses the y-axis)

Example:

Line with slope 2 and y-intercept 3 → y = 2x + 3

Distance Between Points

Use the distance formula (based on the Pythagorean Theorem):

d = √[(x₂ − x₁)² + (y₂ − y₁)²]

In Part 3, we will explore advanced geometry, surface area, volume, and more problem-solving strategies, including how to approach complex word problems with multiple steps or embedded equations.

Advanced Geometry and Practical Applications

Introduction to Advanced Geometry on the ASVAB

Geometry questions on the ASVAB often involve formulas and require a good understanding of shapes and spatial reasoning. While some questions involve identifying shapes or angles, many ask you to calculate perimeter, area, surface area, or volume.

Other geometry questions are presented through diagrams or word problems, which require interpreting visuals, understanding relationships, and applying the right formulas. Knowing which formula to use — and how to use it — is often the difference between getting the question right or wrong.

Area and Perimeter of Two-Dimensional Shapes

Rectangles and Squares

Perimeter is the distance around the shape:

Rectangle: P = 2(l + w)
Square: P = 4s

Area is the amount of space inside the shape:

Rectangle: A = l × w
Square: A = s²

Where:

l = length
w = width
s = side of the square

Example: A rectangle with length 10 and width 5

P = 2(10 + 5) = 30
A = 10 × 5 = 50

Triangles

Area of a triangle:
A = (1/2) × base × height

The base is one side of the triangle; the height is perpendicular to that base.

Example: Base = 6, Height = 4
A = 0.5 × 6 × 4 = 12

The perimeter of a triangle is the sum of its sides.

Parallelograms

Area: A = base × height
Perimeter: P = 2(a + b), where a and b are adjacent sides

Note: The height is the perpendicular distance from one base to the other, not the slanted side.

Trapezoids

A trapezoid has one pair of parallel sides (called bases).

Area:
A = (1/2) × (base₁ + base₂) × height

Perimeter: Add all four sides

Example: base₁ = 5, base₂ = 9, height = 4
A = 0.5 × (5 + 9) × 4 = 28

Circles

Circumference (Perimeter):
C = 2πr or πd

Area:
A = πr²

Where:

r = radius (distance from center to edge)
d = diameter (2 × radius)

Example: Radius = 3

C = 2 × π × 3 = 6π
A = π × 3² = 9π

On the ASVAB, you may be asked to approximate π as 3.14.

Similarity and Proportional Geometry

Similar Triangles

Two triangles are similar if their corresponding angles are equal and their sides are in proportion.

This means:

angle A = angle D
angle B = angle E
angle C = angle F
and AB/DE = BC/EF = AC/DF

Use proportions to solve for unknown side lengths.

Example: A triangle with sides 3, 4, 5 is similar to one with a shortest side of 6. What are the other two sides?
Scale factor = 6 / 3 = 2
Other sides = 4 × 2 = 8, 5 × 2 = 10

Proportional Reasoning in Shapes

You might be given scale drawings or maps and asked to find real distances based on ratios.

Example: On a map, 1 inch = 10 miles. A measured distance of 2.5 inches represents:
2.5 × 10 = 25 miles

Surface Area of 3D Shapes

Surface area is the total area of all faces of a three-dimensional object.

Rectangular Prism (Box)

Surface Area = 2lw + 2lh + 2wh
Volume = l × w × h

Where:

l = length
w = width
h = height

Example: l = 5, w = 3, h = 2

SA = 2(5×3) + 2(5×2) + 2(3×2) = 30 + 20 + 12 = 62
Volume = 5 × 3 × 2 = 30

Cube

A cube has all sides equal:

Surface Area = 6s²
Volume = s³

Example: s = 4

SA = 6 × 16 = 96
Volume = 4 × 4 × 4 = 64

Cylinder

Surface Area = 2πr² + 2πrh
Volume = πr²h

Where:

r = radius
h = height

Example: r = 3, h = 5

SA ≈ 2π(9) + 2π(15) = 18π + 30π = 48π ≈ 150.8
Volume ≈ π × 9 × 5 = 45π ≈ 141.3

Sphere

Surface Area = 4πr²
Volume = (4/3)πr³

Example: r = 2

SA = 4 × π × 4 = 16π ≈ 50.3
Volume = (4/3) × π × 8 = (32/3)π ≈ 33.5

Cone

Surface Area = πr² + πrl (l = slant height)
Volume = (1/3)πr²h

Slant height may need to be calculated using the Pythagorean Theorem.

Coordinate Geometry Applications

Distance Between Two Points

Use the distance formula:
d = √[(x₂ − x₁)² + (y₂ − y₁)²]

Example: (1, 2) and (4, 6)

d = √[(4 − 1)² + (6 − 2)²] = √[9 + 16] = √25 = 5

Midpoint Formula

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

Example: (2, 4) and (6, 8)

Midpoint = (2+6)/2, (4+8)/2 = (4, 6)

Problem Solving with Geometry in Word Problems

Composite Figures

You may be given a shape that is a combination of others (e.g., a rectangle and a semicircle). You’ll need to find the area or perimeter by breaking the figure into simpler parts.

Example: A shape includes a rectangle with a semicircle on top.

Find the area of a rectangle.
Find the area of a semicircle: (1/2)πr²
Add the two

Volume in Practical Situations

Many problems use volume to find how much space something holds (e.g., water in a tank or air in a balloon).

You may be given units in inches but asked for cubic feet. Be prepared to convert units.

Surface Area in Packaging or Painting Problems

Example: How much wrapping paper is needed to cover a box?
Use surface area formulas.

Or: How much paint is required for a spherical tank?
Use the surface area of a sphere.

Measurement Units and Conversions

You may be asked to convert between:

Inches, feet, and yards (12 inches = 1 foot, 3 feet = 1 yard)
Ounces, pounds, and tons
Milliliters and liters, or centimeters and meters

Also, be ready to convert between square and cubic units:

1 ft² = 144 in²
1 ft³ = 1728 in³

If you’re solving a problem about volume in cubic feet, make sure your dimensions are all in feet before using the formula.

Practical Tips for Geometry Problems on the ASVAB

Memorize basic formulas. These are not provided on the test.
Draw diagrams. If a figure isn’t provided, sketch it yourself.
Label dimensions. Keep track of units.
Use the process of elimination. Sometimes plugging in answers works faster than solving symbolically.
Estimate when possible. If choices are far apart, exact answers may not be necessary.

In Part 4, we will focus on comprehensive test strategies, tackling multi-step word problems, combining arithmetic and algebra in practical scenarios, and reviewing mixed-question types — all to help you prepare for the real experience of the ASVAB math sections.

Mixed Problem Solving and Test Strategies for ASVAB Math

Introduction to ASVAB Problem-Solving

As you prepare for the ASVAB, it’s important to understand that most math questions won’t simply test one concept. Many problems are multi-step, combining skills like percent calculations, unit conversions, proportions, and algebra, all in the same question.

The test rewards not just memorization, but also flexibility—the ability to identify what a problem is asking and determine the right method to solve it. This section covers the strategies and integrated skills you’ll need to solve the most common—and trickiest—types of ASVAB math questions.

Solving Multi-Step Word Problems

Multi-step problems often involve more than one operation or concept. The key is to stay organized, break the problem down into manageable steps, and identify what’s being asked before you start solving.

Example: Percent and Equation

A jacket is on sale for 25% off, and the sale price is $60. What was the original price?

Step 1: Let the original price be x.
Since it’s 25% off, you’re paying 75% of the original price.
Set up the equation:
0.75x = 60

Step 2: Solve for x.
x = 60 ÷ 0.75 = 80

Original price: $80

Example: Distance, Rate, and Time

A car travels at 60 miles per hour. How long does it take to travel 180 miles?

Use the formula:
Distance = Rate × Time
So:
180 = 60 × Time
Time = 180 ÷ 60 = 3 hours

Example: Combined Work Problems

If one worker can complete a job in 4 hours and another can do the same job in 6 hours, how long will it take them to finish it together?

Step 1: Find work rates.
Worker A: 1 job per 4 hours = 1/4
Worker B: 1 job per 6 hours = 1/6
Combined rate: 1/4 + 1/6 = (3 + 2) / 12 = 5/12

Step 2: Time = 1 ÷ (combined rate) = 1 ÷ (5/12) = 12/5 = 2.4 hours

Blending Geometry with Algebra

Some questions may ask for unknown values within geometric figures using algebraic expressions.

Example: Geometry and Equations

A rectangle has a width of x and a length of x + 3. If its area is 70 square units, what is the value of x?

Step 1: Use the area formula: A = l × w
70 = x(x + 3)

Step 2: Expand:
x² + 3x = 70

Step 3: Set the equation to 0:
x² + 3x − 70 = 0

Step 4: Factor:
(x + 10)(x − 7) = 0
x = -10 or x = 7
Negative values don’t make sense here, so: x = 7

Using Proportions in Practical Contexts

Many real-world problems on the ASVAB are solved using proportions.

Example: Map Scale

If 1 inch on a map represents 50 miles and two cities are 3.5 inches apart on the map, how far apart are they in real life?

Set up a proportion:

1 inch / 50 miles = 3.5 inches / x miles
Cross multiply:
1x = 50 × 3.5
x = 175 miles

Interpreting Tables and Data

Some ASVAB math questions involve reading data from charts or tables and applying arithmetic to it.

Example: Average from Table

A table shows the number of books sold each day for five days:
Monday: 10
Tuesday: 15
Wednesday: 12
Thursday: 13
Friday: 20

What is the average number of books sold?

Add them: 10 + 15 + 12 + 13 + 20 = 70
Divide by 5: 70 ÷ 5 = 14

Average = 14 books

Working with Units and Conversions

You’ll often need to convert between units, especially in word problems involving volume, area, or rates.

Example: Volume Conversion

A storage box measures 2 feet by 3 feet by 1 foot. What is its volume in cubic inches?

Step 1: Volume in cubic feet = 2 × 3 × 1 = 6 ft³
Step 2: 1 ft = 12 inches → 1 ft³ = 12³ = 1,728 in³
So: 6 ft³ = 6 × 1,728 = 10,368 in³

Mixed-Type Questions: Putting It All Together

Example: Geometry, Proportions, and Area

A triangle is similar to another triangle whose base is 5 cm and height is 8 cm. The larger triangle’s base is 10 cm. What is its height?

Step 1: Set up proportion:
5 / 10 = 8 / x
Cross-multiply:
5x = 80 → x = 16

Step 2: Area = 0.5 × base × height = 0.5 × 10 × 16 = 80 cm²

Strategy: Estimation and Elimination

You don’t always need to calculate the exact answer if the choices are far apart.

Example:

What is 49% of 200?

Instead of multiplying:
49% ≈ 50% → 50% of 200 = 100

Look at the answer choices—if only one is near 100, that’s likely correct.

Strategy: Plug In the Answer Choices

If solving algebraically seems difficult, plug in each answer choice to see which one works.

Example:

What number, when added to 3 and then multiplied by 4, equals 48?

Let x = unknown
(3 + x) × 4 = 48

Try answer choices:
A. 6 → (3 + 6) × 4 = 36
B. 9 → (3 + 9) × 4 = 48 ← correct

Strategy: Look for Keywords

Understanding what the question is asking saves time.

Common keywords and meanings:

“Of” usually means multiply (e.g., 25% of 80)
“Per” indicates division or a rate (e.g., miles per hour)
“Increased by” means addition
“Decreased by” means subtraction
“Total” or “sum” indicates addition.
“Difference” means subtraction.
“Product” means multiplication.
“Quotient” means division.

Strategy: Use Logical Reasoning

Some problems can be solved without heavy math, just using logic.

Example:

If it takes 3 machines 3 hours to build 3 cars, how long would it take 6 machines to build 6 cars?

Think: 3 machines take 3 hours to build 3 cars = 1 car per machine per 3 hours.
So, 6 machines would also take 3 hours to build 6 cars.

Answer: 3 hours
