GED Algebra: Order of Operations (PEDMAS)

It is important that you understand the order of operations. If you think back, you may remember the phrase "Please Excuse My Dear Aunt Sally". First complete everything within brackets or parentheses. Second, simplify exponents. Third, do any multiplication or division from left to right. Finally, do any addition or subtraction from left to right.

Example: 4+6x2=?

First multiply 6 and 2. 

Add 4 to the product of 12.

Your answer is 16. Can you come up with an example?
