Thread: 48÷2(9+3)=?

Our own version of Smarter Than a Fifth Grader!!!!!!!!


YouTube - Europe is a country and everyone speaks french there

The people who keep arguing PEMDAS to get 2 as an answer need to actually google the term and it will show them that they are in fact wrong.

Age 24, and its 288 if you follow BODMAS or PEDMAS. I believe the answer would be 2 if you had extra parenthesis around the denominator (ie. 48/(2(9+3)).

From what I'm gathering it depends on how you look at it. I've came to the conclusion that both are right and exceptable answers depending on the form of math required.

If you're working distribution I see it as

48 ÷ 2(9+3) so
48 ÷ ((9*2)+(3*2)) then
48 ÷ (18+6) then
48 ÷ 24 equals
2

But conventional BEDMAS says

48÷2(9+3) so
48÷2*(12)
(48÷2)*(12)
24*12
288

19 and I didnt do the problem. So I win.

Its been like this:

2(9+3)

ever since HS, it's been / for me...

like 48/2(9+3)

This only true if it is written as 48/[2(9+3)]

I have never seen a case where you distribute amongst constants. That entire top form would be considered "incorrect algebra."

Huh...maybe you all need to visit this site instead:

48÷2(9+3) = ? - OwnagePranks Forum
There are about a kajillion posts in there so I'll condense it.
Basically it's a ****ty problem. It can go either way. The notation is bad and therefore it could be 288 or 2. Using PEMDAS/BEMDAS whatever you call it, multiplications and division are on par with each other, as are addition and subtraction, so when it comes to those, it goes from left to right, not necessarily multiplication before division.
NOW, if you distribute the 2 into the parentheses, which you may do, you'll get 2, but if you do NOT distribute, by order of P/BEMDAS, you should get 288.

So what it really comes down to is notation. If they answer they were looking for was 2, it should've been 48/(2(9+3))
And if they were looking for 288 the notation should've been
(48/2)(9+3).

That's the "answer", there is nothing left to say about this. You can argue with me, but that would make you a dumbass.

Edit: Also for the acronyms, PEMDAS, BEMDAS, PEDMAS, BEDMAS, they're all correct. The way they teach it around here is "Please Excuse My Dear Aunt Sally" and seeing as it's taught all these different ways only reinforces the fact that division and multiplication are on part with each other.

Nope.
Really what this thread needs is a lock. Cause I know someone is going to take this out of hand, the link to the other forum I posted, they took it seriously overboard.
