i too know pemdas.
care to explain why google calculator is stating the answer is 288?
http://www.google.com/search?q=48÷2(9+3)&ie=UTF-8
there are other online calculator sites that output different answers.
there can only be one right answer.

Dos
arent you supposed to do whats in the parenthesis first, then whatever the squares or roots, then multiplication or division, the adding and subtracting?
i mean its been a LONG time since i did 6th grade math...and i NEED to relearn this shit now that i got a kid.

Should get interesting
You got it wrong homie.
48÷2(9+3)
Parentheses first
(9+3) = 12
THEN YOU HAVE 48/2(12)
After that you work left to right
24(12)
288
Multiplication and division are the same, therefore you work right to left after you do the parentheses.
Least that's what I recall lol. I could be wrong.
24(12) or 24x12
I think google is linear, so it sees " 48 / 2 " before it sees the rest. This leads to " 24 * 12 " which is 288.
i think it boils down to whether you're reading it like this
(48/2)*12 = 288
or like this
48/(2*12) = 2
(48/2)*12 = 288
or like this
48/(2*12) = 2

Wrong again. IIRC if it were how you wrote it it'd be
48÷[2(9+3)]
Which is
48÷[2(12)]
48÷[24]
48÷24
2
Disclaimer - haven't done math like this in a long time.
now that im lookin at it, i think the division sign separates the problem, to get 288 it would have been 48÷2*(9+3) = with the multiplicatin sign between the 2 and parenthesis, thats my shot in the dark
Funny you say that. I was thinking that the other day, that when I have children I'm going to have to pretty much go back to school from scratch.
Anyway, PEMDAS is
Parentheses, Exponents, Division, Multiplication Addition, Subtraction.
At the least it would break down to
doing the (9+3) first (parenthesis) -- 12
Division - 48÷2 -- 24
Multiplication - 24*12.
I think you mean left to right and I think you are correct on multiplication and division are the same. Fuck I failed.
48÷2(9+3) =
48÷2(12) =
48÷24= 2
48÷2(12) =
48÷24= 2
lol yeah I did. Typed quicker than I was thinking for a second.
Absolutely not
You only do what's inside the parenthesis first (9+3)
Now you divide 48/2
Final equation is 24(12)
Same difference....
order of operations and dear aunt ugly and all that says you distribute whats outside of the parenthesis first.
you can thank me when you get your GED nubian
.
This is a tricky one because everyone is breaking it down differently.
I was taught the BODMAS system (Brackets, Orders, Division/ Multiplication, Addition/Subtraction)

Hell, fuck it. I'm now confused too
I haven't done this kinda math in a long time.

wrong!
i too thought it was 2 but that was until i was getting different outputs.
i even busted out my ti-83 and it's output was 288.
