Understanding Integer Word Problems

Integer word problems require you to work with integers in a variety of contexts—often

involving addition, subtraction, multiplication, or division of positive and negative

numbers. These problems are framed as everyday situations, making abstract math

concepts more tangible.

What Are Integers?

Integers include all whole numbers and their negatives, plus zero. For example:

Positive integers: 1, 2, 3, 4, …

1.

Negative integers: -1, -2, -3, -4, …

2.

Zero: 0

3.

When solving integer word problems, it's crucial to understand how these numbers

interact. For instance, subtracting a negative number is equivalent to adding its absolute

value, and multiplying two negative numbers yields a positive result.

Why Are Integer Word Problems Important?

Integer word problems connect math theory with real-world applications. They help

students develop problem-solving skills, logical reasoning, and the ability to interpret

mathematical language. Moreover, such problems appear frequently in standardized tests

and everyday life—like calculating debts, temperatures, elevations, and financial

transactions.

Common Types of Integer Word Problems

Integer word problems can be categorized based on the operations involved and their

real-life context. Here are some common types:

1. Temperature Changes

These problems involve understanding increases and decreases in temperature, often

crossing above and below zero degrees.

Example:

“The temperature was -3°C in the morning. By afternoon, it rose by 7°C. What is the

temperature in the afternoon?”

Solution:

-3 + 7 = 4°C

2. Elevation and Depth

Problems involving heights above sea level or depths below ground or water surfaces.

Example:

“A submarine is 120 meters below sea level. It rises 45 meters. What is its new position

relative to sea level?”

Solution:

-120 + 45 = -75 meters (still below sea level, but less deep)

3. Financial Transactions

These problems often involve gains and losses, profit and debt, or deposits and

withdrawals.

Example:

“John had $50. He spent $70 on shopping. What is his balance now?”

Solution:

50 - 70 = -20 (John owes $20)

4. Sports Scores and Point Differences

Tracking scores, wins, and losses using integers.

Example:

“A team was trailing by 5 points. They scored 8 points in the next quarter. What is their

lead now?”

Solution:

-5 + 8 = 3 (now leading by 3 points)

Step-by-Step Approach to Solving Integer Word Problems

Approaching integer word problems systematically can make the process straightforward

and less stressful.

Step 1: Read the Problem Carefully

Ensure you understand the scenario. Identify what is being asked and what information is

provided. Sometimes, rephrasing the problem in your own words helps clarify the

objective.

Step 2: Define the Integers

Assign integers to the quantities involved. Remember to use negative numbers where

appropriate (e.g., debts, depths, losses).

Step 3: Choose the Correct Operation

Determine whether to add, subtract, multiply, or divide based on the problem’s context.

Integer operations can be tricky, so double-check signs.

Step 4: Solve the Arithmetic

Perform calculations carefully, keeping track of positive and negative signs. Use the rules

of integer operations:

Adding two positives = positive

1.

Adding two negatives = negative

2.

Adding a positive and a negative = subtract smaller absolute value from larger

3.

absolute value, take sign of larger

Subtracting an integer = add its opposite

4.

Multiplying/dividing two integers: same signs = positive, different signs = negative

5.

Step 5: Interpret the Answer

Check if your result makes sense in the context of the problem. Sometimes the answer

needs to be explained in words or converted into a real-world measurement.

Sample Integer Word Problems and Answers

Going through examples is one of the best ways to get comfortable with integer word

problems.

Problem 1: Bank Account Balance

Sara has $120 in her bank account. She withdraws $150 to pay bills. What is her new

balance?

Solution:

120 - 150 = -30

Sara's account balance is now -$30, meaning she is $30 overdrawn.

Problem 2: Hiking Elevation

A hiker starts at an elevation of 200 meters above sea level. She descends 350 meters

down a valley and then climbs back up 150 meters. What is her final elevation?

Solution:

Starting elevation: +200 meters

Descent: -350 meters

Climb: +150 meters

Calculate stepwise:

200 + (-350) = -150 meters (valley floor)

-150 + 150 = 0 meters (sea level)

The hiker ends at sea level.

Problem 3: Temperature Drop

In the evening, the temperature was 5°C. Overnight, it dropped 12°C. What is the

temperature in the morning?

Solution:

5 - 12 = -7°C

The temperature is -7°C in the morning.

Problem 4: Sports Game Scores

A basketball team was trailing by 10 points. They scored 15 points in the last quarter.
