Subtracting Integers

To subtract two integers, add the first integer to the opposite (additive inverse) of the integer to be subtracted.

Expressions can involve repeated subtraction or combinations of subtraction and addition. To evaluate them, we use the order of operations rule.

Subtraction finds the difference between two numbers. When we find the difference between the maximum value and the minimum value of a collection of measurements, we are finding the range of the values.
