Adding and Subtracting Integers

Front

What is the result of adding a positive integer to a negative integer?

Back

The result depends on the absolute values of the integers. If the positive integer has a greater absolute value, the result is positive; if the negative integer has a greater absolute value, the result is negative.

How do you subtract a negative integer from a positive integer?

Back

Subtracting a negative integer is the same as adding its absolute value. For example, a - (-b) = a + b.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

How do you add two negative integers?

Back

Add their absolute values and keep the negative sign. For example, -a + (-b) = -(a + b).
