    Confused with order of operations

    Hi All,
    Looking for some clarity.

    I had the following test problem in "order of operations"
    36/4(5-3)+6 and gave 9 as the answer. According to the rules I was wrong. the answer was 33

    If I had the equation Y=36/4(a+b)+6 and rewrite as:

    36
    Y= ___________ +6
    4(a+b)

    And use a=5, b=-2 then Y=9

    What am I missing?

    If I had the equation Y=36/4(a+b)+6 and rewrite as:
    As posted "Y=36/4(a+b)+6" means Y=9(a+b)+6.

    If you had posted "Y=36/{4(a+b)}+6" then it would be Y=\frac{36}{4(a+b)}+6.

    It is all about grouping symbols .
