288 or 2


i think 288

my vote's for 2, but I it's been 15 years since I had to worry about something like this.

It's 2.

Is this another one of those corny Joe Maddon equations to success.

this is what i see:


48÷2(9+3)
=24(9+3)
=24(12)
=288

Actually, never mind me, I was imagining parenthesis where they didn't exist. Probably because the format looks like the TS% formula:

PTS / (2 * (FGA + 0.44 * FTA))

you would have failed the test if you didn't show the complete equation...

(because I actually want know how to solve this)

Yeah, that's what I thought. Order of operations whoring...I think below is actually the proper way to solve such a perplexing equation.

48÷2(9+3)
48÷2(12)
24(12)
=288

Parenthesis always come first, so it would translate to 48 / 2(12) at outset. Like satyr, I haven't sat in a math class in years (uh, since 2003, I believe, and math wasn't a strength), so this next bit I'm not too sure about. It comes down to whether the 2*12 portion is considered to be part of the parenthetical equation -- in which case you solve that first, and the answer is 2 -- or not, in which case you go left-to-right, and it becomes 24*12 = 288.

Still think that it's 2, just not 100% sure anymore.

You got this from the Bulls board.

My graphing calculator tells me 2, so I'll stick with that.

After thinking about it, the way I see it is:

48
______
2(9+3)

= 2

EDIT: When I actually type the equation THIS way into my calculator, I get 288.

So 48÷2(9+3) = 2 but

48
______
2(9+3)

= 288

according to my calculator. I guess it's 288 then.

PEMDAS, right? 48/2(12) --> 48/24 = 2

PEMBAS/BEDMAS, etc, also says that you should work left to right when operations have the same precedence.

Look at my post above, writing the equation 2 different ways (one with the "÷" symbol and the other with "/") gives 2 different answers, yet it's the same equation.

That has to be it. I think writing the equation using the "÷" confuses some calculators. When you write it as a normal fraction it becomes clear.

I've always went by BEDMAS and for MD and AS they're the same "class" per se so its not like its dividing first and then multiplying. The order's more like

B
E
D/M
A/S

With D/M and A/S you always go left to right no matter what as long as they're on the same "level".

In this case 2 is outside of the brackets so it doesn't count in the (9+3) level so it should be counted as being in the D/M level. So on that stage you go left to right so the answer is 288.

My graphing calculator has a "÷" and "/". Using the different symbol would give a different answer. 288 is it no doubt though. It must just confuse itself with the "÷".

288.

Yea I realized the left-right thing, now I'm the fool.


That's wrinkling my brain!

Really, it comes down to logic vs. order of ops, as written. Logically, the answer should be 2; looking at it, you think "2 groups of 9 plus 3, divided into 48". Following the strict order of operations, it's 288. What it's missing is a set of parenthesis...either (48 / 2), or (2 (9+3)).


But seriously. **** math in its **** face.
