2 assuming the 2(9+3) is the divisor.

48/2(12) = 48/24 = 2..

Use PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Do (9+3) which is 12, then multiply (since the 12 is still in parenthesis) by 2, which is 24.

48/24= 2.

Interesting. Sometimes people say multiplication takes precedence over division in such cases, but in computer languages these days, they go left to right.

The division and multiplication can interchange at any time, it doesn't matter the order.

gradeschool math

48 ÷ 2 x (9+3)
48 ÷ 2 x 12
24 x 12 = 288

next?

lol yes it does. It's left to right

Is it 48/(2(9+3)) or (48/2)*(9+3)?

Because the way it looks, it is 48/(2(9+3)), which = 2.

It is how you see it

The way it's written it's 288... I was applied math and economics in school. If not, what a waste of an education.

I'm not sure how matlab got it wrong. Excel agrees with 288, so does google.

Parentheses first then left to right on the multiplication/division.

48/2(9+3) = Parentheses
48/2*12 = Left to Right
24 * 12 = 288

48/(2(9+3))= 2

This is like 6th grade math...

Seems many have not learned about distribution.

Yeah, and I distribute to get 2

I'm pretty sure its 288 since the 2 is not bracketed with (9+3) and division comes before multiplication.

this is so bad, I am taking high level calc classes in college. I swear to all of you on my future education, the answer is 288

the order of operations is that you do what's in the parenthesis first. then if there's multiplication and division, you assume the left-to-right interpretation unless there's another parenthesis.

answer is 288. 2 is incorrect.

Is this the 1st time fluffy beaver is wrong? thought he was always right...

Answer is 288, if it was
48÷((2(9+3)) then it would
be 2.

...48÷2(9+3) distribute?

48/18+6 = The parentheses disappear after you distribute which is wrong anyway.

Put it into Excel, google or a calculator exactly how it is written. It's 288.

You guys are IDIOTS. PEMDAS IS NOT WRONG.

When you add 9 and 3, you get 12. THE PARENTHESIS ARE STILL THERE SO THE PROBLEM THEN BECOMES 48 / 2(12)

PARENTHESIS FIRST.

THE ANSWER IS 2

anyone that thinks or tries to argue that the answer is 2 should get a Referral. tennis is a gentlemen's sport. men should be educated. please stop going with 2 on the pull. I must end this

I'll say it again, distribution comes first.

For example adding a variable.

48÷2(9x+3) = 1 >> 48÷(18x+6) = 1 >> 48 = 18x + 6 >> 42 = 18x >> 42/18 = x = 2 1/3.

Now we obviously can't add (9x + 3) together because of the variable, but we also wouldn't want to do 48÷2 first because the parenthesis should technically comes first, so we distribute the 2. So even if the 'x' wasn't there, it's the same concept.

PS: 2(9+3) = 24

and

2(9+3) = (18 + 6) = 24

48 ÷ 2(9+3)

Is Not The Same As

48 ÷ (2(9+3))

Solve my example with the variable with your method and see if it equals 1 when you plug your answer into x. Please show your work.

That's just plain wrong. Even an 11 year old knows that multiplication and addition are commutative. While subtraction and division are not.

Can someone please explain how excel, google, and the calculator are wrong?

Well then, can you explain how Matlab is "wrong" from google, excel, and the calculator.

Obviously one or the other is wrong and I'd go with Matlab being correct.

my 13 yr old daughter has come to the conclusion that half of you need to get back to school. The answer is 288.

BEDMAS

Brackets
Exponents
Division
Mulitplication
Addition
Subtraction

She is in enriched math.

You didn't understand what I meant. I mean that you can do the multiplication BEFORE the division, or vice versa UNLESS there are parenthesis or exponents involved. Such as in this problem.

You know it's funny people are calling each other idiots. What's even funnier are the ones who are wrong doing the name calling. This is really elementary math. The answer is 2.

All I can say is I at least tried to show work and explain my steps. If someone wants to do the same with a better explanation to prove us wrong I'd be happy to say I was wrong. But all the shouting with no proof isn't helping.

() first then work left to right
48/2=24x12=288

people will still think the answer is 2. There are no more ways to break it down for them

Well another way to look at it is

48÷2 = 24x12 = 288 and
48x12 = 576÷2 = 288.

I'd assume left to right still applies in this.
