Solve algebra problems involving more than one mathematical function. State problem areas to look for when conducting a home energy audit. Although you may not realize it, you use the set of integers in everyday mathematical calculations. The integers are a set of numbers that can be depicted on a number line. Positive integers are the numbers to the right of zero.
Negative integers are on the left.
See Example 1. Many students, however, may not be familiar with using negative integers. Below you will find a set of rules to help you use negative integers correctly when calculating problems involving the four basic mathematical functions. If the negative number is the larger, the answer will be negative. Subtracting a negative integer is the same as adding a positive integer.
