**Order of Operations** (in **Pre-Algebra**) really are a lot of fun – like a puzzle! And remember that the calculator does them automatically!

I like to use the mnemonic “**P**lease **E**xcuse **M**y **D**ear **A**unt **S**ally” or **PEMDAS** to remember the order. The order is **P**arentheses,**E**xponents, **M**ultiplication and **D**ivision (either one, in order from left to right), and then **A**ddition and **S**ubtraction (either one, in order from left to right) – **PEMDAS**.

**PEMDAS** stands for:

So you’ll do the math left to right, like you’re reading a book, but you must pay careful attention and perform some operations before others. Here are some examples:

Happy Mathing!
