Adding and Subtracting Integers Practice Flashcard

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero, but not a fraction or decimal.

Front

What does it mean to add integers?

Back

Adding integers involves combining their values. If both integers are positive, the result is positive. If both are negative, the result is negative. If one is positive and the other is negative, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value.

Front

What does it mean to subtract integers?

Back

Subtracting integers can be rewritten as adding the opposite. For example, a - b is the same as a + (-b).

Front

What is the result of (-5) - (-1)?

Back

The result is -4.

Front

Rewrite the subtraction -9 - (-2) as an addition problem.

Front

What number do you add to 5 to get a sum of 0?

Back

You add -5.

Front

What is the result of 3 + (-7)?

Back

The result is -4.

Front

How do you find the sum of a positive and a negative integer?

Back

You subtract the absolute values and take the sign of the integer with the larger absolute value.

Front

What is the absolute value of an integer?

Back

The absolute value of an integer is its distance from zero on the number line, regardless of direction. For example, |-5| = 5.
