One of the things you must get in habit of doing with exponent problems is to first evaluate the terms that are presented to you. When you want to perform a sum or difference between variables that contain an exponent both variables and exponents must be the same. As you get further along with algebra, you will learn to combine like terms. That should always be your first step when evaluating any expression, equation, or system for that matter. Exponents are so common in physical science problems that it is not a choice as to whether you need to master them or not. When we need life-saving treatment, you had better hope that the pharmacist and doctor have their exponents on lock down.

These problems involve whole numbers infused with a single exponent that are undergoing sum or difference operations. We start with single digits and advance to values that contain triple digits. This set of worksheets will give your students practice in finding the sum or difference in equations containing exponential numbers. Students must solve for the exponent before answering the questions. These worksheets explain how to add and subtract exponents using multiplication. The operations will always result in a change between the exponent pairs and grouping.
