Adding and Subtracting with Exponents

Before adding and subtracting with exponents, there are a few things to define and review to avoid confusion. A base is the number that is being raised to the power of something. The number it is being raised to is called the exponent, which represents how many times the base is being multiplied by itself. In the example 4x2, the base (x) is being multiplied by itself twice. The number in front of the base variable (4) is called the coefficient. In order to solve an addition or subtraction problem involving exponents, make sure the bases and exponents are the same on each side of the problem. If there is a problem in which some terms do not have the same exponent, identify the terms that can be combined and simplify the problem.
