Brunstucky taught me wrong because I was always taught PEMDAS and to do it in the excact order, no left to right bullshit. Multiplication before division and addition before subtraction. I am not wrong by saying 2 all of my math teachers are wrong because I say 2.

i was taught in two school districts that PEMDAS isnt strict with the last 4...it could be PEDMSA if thats what the problem calls for...mult, and div. have the same weight, and addition and sub have the same weight.... it always goes left to right, you just have to do parenthesis > exponents > mult/div > add/sub....you can flip the mult/div and add/sub

i was thinking 2 originally because of what others said, i was thinking that since the 2 was right next to the parenthesis without any notation between, that it had to be distributed first inside the parenthesis

i see how 288 is right, but i also see how 2 could be seen correct by people who are rusty on their math skills, like myself

To multiply in algebra, use the distributive law

2(9+3) = ((2x9)+(2x3)) =24

48÷2(9+3)

48÷((2x9)+(2x3)) = 2

Sorry guys, this is one of those cases where calculators will give the wrong answer.

48÷2(9+3)=lol

Division is the same as a fraction. So it's like putting the 2(9+3) under the 48. That's another way to look at it as well. It's TWOOOOOOOOOOO!!!! :cheers::p

wait...you were supposed to go to bed two pages ago!

Got hung up proving myself right. :lol:

In a shop full of math wizzes here are the answers I got:

4x 288

3x 2

2x 36

2x I've never seen anything like that (didn't know)

.5

.66666666

Nuff said.

Man, hope they hold tolerances better than doing math. :lol:;)

It's hopeless man. I give up. The correct people know it's 2. :banana:

I can't stop loling because we have 152 post about a math problem on a motorcycle forum lol.

M is same weight as D

A is same weight as S

The problem is not poorly written, but it could be written better.

48/2(9+3)

First the parens

48/2(12)

this could also be written as

48/2*12

Now the question is do we do 48/2 first or 2*12 first. Since M and D have the same weight, we have to work left to right.

That makes the answer 288

48/2*12

Now the question is do we do 48/2 first or 2*12 first. Since M and D have the same weight, we have to work left to right.

That makes the answer 2

I changed your answer because you did that problem wrong. A division is just like a fraction. The 2(12) or 2*12 is in the denominator which makes it 48 OVER 24 or just 2. ;)

So I asked a coworker this morning that has a degree in mathematics and participates in algorithm challenges; he said it was 2 as well.

I was the first post to say 2 and they can't accept that NinjaNick was right. :lol: I'm saddened how many humans mess this up Jeremi.

Since when do "experts in their field" matter?

We believe what policians tell us about jobs, economy, and the budget instead of the experts in the field that deal with those everyday so... why bother consulting the experts on this?

The answer to this problem is Glenn Beck.

You can't change the problem to make it get the answer you want. :lol:

You have too much vested to admit failure at this point. :lol:

I'm not! It's just like 4 divided by 2 is a fraction. You write it either way! The second way of writing it is 4(numerator)/2(denominator) = 2

Division is a fraction! That's a 2nd way of looking at the problem other than the way we others simply just saw that it was 2.
