Order of Operations
With IntegersUnit 7
In the last lesson we learned the rules for Order of Operations. We use the sentence: Please Excuse My Dear Aunt Sally to help us remember these rules. Until now we have worked with whole numbers only. Let's look at a few examples involving integers... This lesson is now available only on The Math Goodies CD. Our CD has over 275 web pages of self-paced instruction designed to make math fun!
