Students will be able to (SWBAT) :

-write and evaluate powers, and

-use the order of operations to simplify numerical and algebraic expressions

In the world of numbers there are many ways to solve a problem. And, several of those ways are correct, but many of them are incorrect if you don't follow the rules of Math. This lesson will review with you some of the rules that are necessary to achieve success in your Math coursework. These are rules many people may be following and not telling you.
