Lesson Excerpt:

II. Dividing Monomials

- "Today we are going to continue our work with monomials, but this time we are going to be dividing them. We will work on several different types of problems. We'll start with the simpler ones and work toward the ones that are more challenging."
- "The first thing to remember is that like multiplying monomials, there is a rule to dividing them. The rule to dividing monomials is that each part gets divided by itself. When you divide variables with exponents, you subtract the exponents. Take a minute and copy these notes down on the board."
