48÷2(9+3) = ???

[JamieSEO]

288.

BIDMAS

Brackets, Indicies, Division, Multiplication, Addition, Subtraction in that order.

so... 48÷2(9+3)

9+3 - 12

48/2 = 24

24 x 12 = 288 is your answer

Let's break it down, make it more simple. To hell with modern or old method.


Assume that...

48÷2(9+3) = x

>> 48 =x/{2(9+3)}

>> 48 = x/(2*12)

>> 48 = x/24

>> x = 48*24

Voila

48 divided by 2(9+3)

This is actually a division process

where , 48 is dividend & 2(9+3) is divisor.

ie, 48 is to be divided by k, where k= 2(9+3), Now we solve the value of k. Inside brackets we have 9+3 , which equals 12. Then 2 is preceding the bracket. That means our bracket is associated with 2. So 12 is to be multiplied by 2. Then only we can say that parentheses have been performed completely. So 2*12 = 24. And this 24 is the divisor.

Thus, 48 ÷ 24 = 2

So, answer is 2

288 for sure

I agree with you, first we need to 'clean' out the parentheses that guys drives me crazy

Correct answer is 288
The people who answered 2 thinks multiplication by juxtaposition has higher priority over a normal multiplication, which is not true.
2(9+2) is equal to 2 x (9+2).

a/bc is equal to a/b x c unless it be specify by parenthesis. a/(bc) would be a / (b x c).

Your teacher in school miss parenthesis because in most of cases it wouldn't change the outcome of algebra such as a + bc, It makes no difference to be written as a + (b x c) you know humans are lazy and they get used to that form. In rare cases that it matters they did it wrong because of human error. after a while they implied 2(9+2) is in fact (2(9+2)) which is not true. 2(9 + 2) is equal to 2 x (9+2)

Yeah my bad...answer is 2. Equation itself got wrong.

All my years of youth was taught with PEMDAS

Please don’t ruin my childhood.

ANSWER IS 2

 

[blackwalker]

PEMDAS

parentheses
exponents
multiplication
division
addition
subtraction

in that order

48÷2(9+3)
48÷2(12)
48÷24
2

48÷2(9+3) = ???

You did not provide clarity, especially by using the ÷ sign (which is frowned upon and never used in the real world). The problem is ambiguous!

A). Are you asking: 48/[2(9+3)] ??

OR

B). Are you asking: (48/2) * (9+3) ??

If you write the problem like this: 48/2(9+3)
then the only way to interpret it is by (A).

 

[AloeAlan]

First we do parentheses. (9+3) = 12
Next comes multiplication. 2(12) =24
Division is last. 48÷24 = 2
2 is our answer

I would have gotten this wrong by answering 2 but the correct answer is 288. Search google for "online calculator" and it will return one that lets you enter the entire equation.

48 / 2 (9 + 3) is the same as
48 / 2 * (9 + 3) then you do parenthesis first so it is
48 / 2 * 12 then you have division and multiplication which have the same priority so are done left to right
24 * 12 = 288

Great post OP. I thought this was a silly question and was laughing at all the bad math people here until I figured out I am one of them

 

[1Enigma]

48/2(9+3)
48/(18+6)
48/24
2
What’s the damn answer

Seems a good explanation.
