Review #3 (1.3) ORDER OF OPERATIONS
Remember that ORDER does matter!
Please Excuse My Dear Aunt Sally...
What does that mean?
1st - P = Parenthesis; grouping symbols such as parenthesis, brackets, fraction bar and absolute value.
2nd - E = Exponents
3rd - M = Multiplication
3rd - D = Division
5th - A = Addition
5th - S = Subtraction
In other words: PEMDAS must be the order that is followed.
Remember that Multiplication and Division happen at the same time; whichever comes first, from left to right. Remember that Addition and Subtraction happen at the same time; whichever of the two comes first, from left to right.
