### How Do You Evaluate?

Describe how you use PBEMDAS to evaluate expressions and equations.  This week you need to write one equation that includes 6 of the 7 rules in the order of operations and explain step by step how you solve the problem.  You may use one of the math problems from this week's homework.  Remember to explain where you are in the steps and what you did to solve it.  Put your name at the end.
