Yepper...
I made this mistake myself @ first.
The numerator is 48 but the denominator is only 2 (48 divided by 2), that is then multiplied by (9+3) or 12.
READ it out loud and you should hear the difference.
I understand that. Hence, my explanation. What was your answer?
I just looked at the poll results.
Oh well. Life is about learning. None of us know everything.
I even had my advisers talking about this. Its a very interesting problem that can easily go unnoticed until something like this comes up.
I think what is making the thread so funny is that people are so sure the answer is 2. One thing to take from the thread is that people are making an effort to argue their point which most are actually valid points. They are just wrong in the sense of how the problem is read.
This shouldnt be that hard.
48÷2(9+3) = 48÷2*(9+3)
48÷2*12
24*12
288
distributive property!
48/2(9+3)
48/(18+6)
48/24
2
that is NOT how you distribute.
The three most important things in mathematics are: notation, notation, notation.
48/2(9+3) = 48/2*(9+3)
The order of operations state that grouping symbols come first, then after exponents, you do multiplication AND division from left to right.
so you could do:
48/2(9+3) = 48/2*(9+3)
24*(9+3)
24*9 + 24*3
216+72
288
This is why america lags so far behind other countries when it come to math. People are allowed to graduate without learning it.
I make it 2 sir...!!!
from another board
"Some of you are treating the parenthetical as an actual multiplication symbol. It's not. It serves as a multiplier, but to the number it is attached to. The 2 is attached to the parenthetical, which means you must solve it as part of the first step in the order of operations. This isn't rocket science."

The answer is 2.

Distributive property of multiplication over addition. Early Algebra problem.
The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).
So this can be rewritten as:
48 / (2*9 + 2*3)
Which leaves us with
48 / 24 = 2
Answer = 2.
Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 * (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (2*9+2*3). Be very careful with your signs.

wasup all you niggaz talking shit to other who came up with 2

c/s the bold
Edit: The answer is 2...looked at it all wrong
48÷2(9+3) = 48÷2*(9+3)
48÷2*(12)
48÷(2*(12))
48÷24
2

This is what I originally thought... Time to dust off the ole algebra text book
Interesting indeed. People that said 2 were understandably wrong since problems like this don't appear in text books or tests too often. At least not that I recall. Also, because of the implied conventions (or shorthand) that we as humans always use/create.
its attached to 48/2 not 2 by its self.
It can be attached to (9+3) if it was (2(9+3))
2(9+3) is the same as 2*(9+3)
(2(9+3)) is the same as 2*9 +2*3

Put 48÷2(9+3) into words and you will see why its 288
48÷2*(9+3) is needed when you putting it in certain software.
If you use a TI Calculator you will get 288 when you put in 48÷2(9+3)
to get the answer to be with the same calculator, you need to input it as 48÷(2(9+3))
For Excel you need to put it in as 48/2*(9+3) to get 288
and 48/(2*(9+3)) to get 2

Hmm I take full on Calc classes (btw I've aced every math class) I'm not the one to test on this one lol You don't want me to post some moderately difficult calc on here. Listen and you might learn something. The answer is two. That's the bottom line. The example I gave you on how to input it into the calculator is the correct method. I've been doing this for quite some time now.
How far did you get in math. Not very far right? lol
this.
putting a number next to the parentheses does NOT make it apart of the parentheses. That is simply a different notation for multiplication.
No. SaKem has a life. I made money this morning in the market, then went to go help a college with their finances, later I'll be working with someone on calc
SaKem can't sit around all day every day.
it doesnt matter how many people realized their mistakes
youre going to fight this one to the end in super retard mode huh?
you take calc classes tho
man unscramble this phrase for me:
UP SHUT THE FUCK
yes, you got it u fucking world class tard!!!
