# Thread: Confused with order of operations

1. ## 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?

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 .
