@cat

You do what is in the parenthesis first.
Multiplication and division go first so,
16x3=48
Then subtract the 12
(48-12)/9+7
so you still want to finish what is in the parenthesis so after subtracting you get
(36)/9+7
Multipulcation and division before addition and subtraction so
36/9=4
so you have
4+7
which equals 11. 😊

I agree with @colette do P.E.M.D.A.S or G.E.M.D.A.S. Really its the same thing. 😋

cat • 28 August 2012 at 8:07 PM

Thanks to all. By mistake, I replaced 16 with 6, so it made no sense XD

Thank you.

(I copied the math into my notebook wrong, and then I cooped it here from the paper. XD)

@cat

What everyone said. It's 11. 😊

You do the parentheses first, then the multiplication/division, then the addition/subtraction for this problem.

@colette I don't even know. xD
