G.E.M.S. VS. P.E.M.D.A.S.


    P.E.M.D.A.S. is the traditional way of learning the Order of Operations.  (Please Excuse My Dear Aunt Sally)  
    However, a common misconception that students make is they try to always multiply first, then divide.  Or add, then subtract.  Because that is the order in M.D.A.S.  However, the reality is that you must multiply or subtract, add or divide, whichever comes first.  Because of this misconception, in our room we use G.E.M.S.

    G.E.M.S. is a great strategy for students to use to learn the Order of Operations.  It stands for:

    G -  Grouping Symbols (parentheses, brackets, braces) ->  ( ) [ ] { } 
    E -   Exponents (the exponent tells how many times the base is multiplied by itself)
    M - Multiply/Divide...whichever comes first!
    S -   Subtract/Add...whichever comes first!
