Order of Operations
Please Excuse My Dear Aunt Shirley (PEMDAS)
- First do what is “inside Parentheses”, or other grouping symbols, ( ), [ ], { }, | |, /
- If / work top & bottom separately & do the division last.
- Then work with the Exponential parts, ^, or Roots, √
- Multiplication and Division are worked next from LEFT to RIGHT!
- Lastly Addition and Subtraction are performed, again from LEFT to RIGHT!
