# How to Add and Subtract Polynomials?

To add or subtract polynomials, you need to add or subtract like terms together. Although, there are are few things that you should remember when working with polynomials, which are to follow the order of operations and to watch carefully when there is a minus sign before any terms or variable expressions. For example, you evaluate (2x^2 -2x )- (x^2 +2x) by writing (2x^2- x^2) + (-2x -2x)= x^2 -4x. For more information look here: www.purplemath.com;
