Adding and Subtracting Integers

Front

What is the definition of Absolute Value?

Back

The distance away from 0.

Front

What is an Additive Inverse?

Back

An additive inverse of a number is the number that, when added to the original number, results in zero. For example, the additive inverse of 4 is -4.

Front

How do you solve -2 - (-10) using a number line?

Back

Start at -2, then move to the right 10 units (because subtracting a negative is the same as adding). This results in 8.

Front

What does '4 less than -5' mean on a number line?

Back

Go to -5 on the number line and then move 4 units to the left, which results in -9.

Front

What is the result of 10 - 10?

Back

0.

Front

How do you represent the operation of adding two integers?

Back

You can represent it on a number line by starting at the first integer and moving to the right for positive integers or to the left for negative integers.

Front

What is the result of -3 + 5?

Back

2.

Front

How do you subtract a negative integer?

Back

Subtracting a negative integer is the same as adding its positive counterpart. For example, 5 - (-3) = 5 + 3 = 8.

Front

What is the result of -7 - 4?

Back

-11.

Front

How do you find the sum of two negative integers?

Back

When adding two negative integers, the result is negative, and you add their absolute values. For example, -3 + (-5) = -8.
