Learn how to calculate the new depth of a submarine that starts at -300 meters and rises 150 meters.
Identify the starting depth (-300 meters) and the change in depth (+150 meters).
Use the equation: Start depth + Rise = Current depth.
Add -300 and 150. Subtract the smaller absolute value from the larger: 300 – 150 = 150. The result is -150 as the larger absolute value is negative.
The final depth is -150 meters, meaning the submarine is 150 meters below sea level.
These worksheets are important because they strengthen foundational math skills like problem-solving, critical thinking, and mental arithmetic. They also help students understand how integers work in real-life situations, such as tracking gains and losses or changes in temperature.
Integer addition worksheets are typically designed for students in grades 6 to 8, though they can also be used for review in higher grades. For grade 8, these worksheets often include more challenging problems with real-world applications.
They show students how math applies to everyday situations, like balancing a budget, understanding temperature changes, or calculating game scores. By connecting math to real life, students build confidence and see the relevance of what they’re learning.
These worksheets include a mix of straightforward numerical problems and word problems. For example, calculating the sum of two negative numbers, combining a negative and positive number, or solving a story problem like finding the altitude of a plane after a rise and fall.
Parents can use these worksheets to provide extra practice for their kids, reinforce classroom learning, or prepare for tests. They’re easy to print and can be turned into fun challenges or timed quizzes for added engagement.
Here’s an example: A bird is flying at an altitude of -5 meters, then rises 15 meters. What is its new altitude? The solution is simple: Add -5 and 15, which equals 10. The bird’s new altitude is 10 meters.
To do integer addition, follow these simple steps:
If the signs are the same (both positive or both negative), add the absolute values of the numbers and keep the common sign.
Example: −3+(−5) = −8
If the signs are different (one positive, one negative), subtract the smaller absolute value from the larger absolute value and take the sign of the number with the larger absolute value.
Example: −7+3=−4
It’s like combining gains and losses—just follow the rules, and it becomes easy!
When adding integers, keep these points in mind:
Understand the signs: Positive numbers add value, while negative numbers reduce it.
Use number lines if needed: Visual aids like number lines can help beginners understand how integers combine.
Practice the rules for same and different signs: Same-sign numbers are added directly, while different-sign numbers require subtraction of absolute values.
Check your work: Double-check calculations, especially in word problems where integers represent real-life scenarios like temperatures or depths.
With practice, integer addition becomes second nature!
