What is the answer?
The answer is two.
2 assuming the 2(9+3) is the divisor.
48/2(12) = 48/24 = 2..
Do (9+3) which is 12, then multiply (since the 12 is still in parenthesis) by 2, which is 24.
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.
48 ÷ 2 x (9+3)
48 ÷ 2 x 12
24 x 12 = 288
lol yes it does. It's left to right
Is it 48/(2(9+3)) or (48/2)*(9+3)?
this is so sad
my answer is 2!
If that's wrong I give up on life.
no, you have to do the () first, please stay alive OHAI, don't do it!
This is correct.
well now I know why posters make some of the dumbest discussions.
You mean Please Excuse My Dear Aunt Sally failed me?
Math never was my strong subject.
what the @#$% the poll keeps going in the wrong direction, it is 288 guys not 2 stop this thread now. You are just embarrasing yourselfs
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
This is like 6th grade math...
Seems many have not learned about distribution.
Yeah, and I distribute to get 2
who, back on track 8-8
Yeah, others apparently have never learned about it.
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, don't accept answers from idiots.
Answer is 288, if it was
48÷((2(9+3)) then it would
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)
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
So google, calculator and excel are wrong?
please post your education background along with your answerers please.
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
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.
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.
Thank God somebody else understands.
so in your world
48 ÷ 2 x 12 = both 2 AND 288?
amazing. Utterly amazing. The American education system at work here folks
there are only so many times i can post the Simple Jack pic. In your case i should make an exception
() first then work left to right
I think I am having a stroke
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.
I'm pretty sure it's 288.
