:D
48/(2(9+3)) = 48/((2*9)+(2*3)) = 48/(18+6) = 48/24 = 2

Alternatively, (48/2)(9+3) = 24(9+3) = (24*9)+(24*3) = 216+72 = 288

The answer isn't 2, but 288.

Since multiplication and division operations are of the same priority, we must do them from left to right:
1. Parentheses (always first) : 48/2(9+3) = 48/2*12
2. Division : 48/2*12 = 24*12
3. Multiplication : 24*12 = 288

Nothing much to say.   Reply With Quote

but the answer IS 2, lol...

2 * 3(6+6)

the 3 takes precidence, and should be done with the brackets before multiplying it with 2.  Reply With Quote

order doesn't matter if you're multiplying.
also the anwser is 288 from the first one and 72 from this one

from the first one, you said this not   Reply With Quote

According to Bimdas as I was taught; (Ed. or as my memory retained?)

48/2(9+3) (Brackets first)
=48/ (2x12) - added brackets for ease of reading. (No inidicies, thus multiplication)
=48/24 (Division, but no addition or subtraction, so...)
=2

I was always taught that Bimdas was followed to the letter (damn I'm funny) but I have googled it and Dragonslover's point, that multiplication and division have equal priority and thus left to right is followed, was immediately backed up.

My mother is a maths teacher, though, so I might ask her tomorrow morning if it 'tis equal or weighted priority. But the catch there is different countries use different stuff.

Edit: I can confirm that there is no priority, so it is not weighted as I believed.So I cede to Mothrayas and Dragonslover.  Reply With Quote
