# Unit: Polynomial arithmetic

#### 0

### About this unit

We can add, subtract, multiply, and factor with polynomials like we do with numbers. The exponents show us the place value for the variables, so that we can add like to like. We'll find the average rate of change (closely related to slope) of polynomials, too.### Learn
