Let's see your answer

48÷2(9+3) = ????

It is 288 based on order of operation. Items in parenthesis are first (9+3)=12

Next is division and mulitiplication with neither trumping the other so it then moves left to right. 48/2=24x12=288.

Has to be 2x12!!!!!!!!!

Yes, the answer is 2.. It was not entered correctly. It is technically not a 'Summation', but 'Division', so Excel did not understand/observe the computing process involved.

Incidentally, it's a/b=c, where a is called the dividend, b the divisor and c the quotient. We're looking for the quotient.

For the answer to be 2 the equation would have had to have been written

48/(2(9+3)). There were no parenthesis around the two so it moves left to right unless there are parenthesis so the answer is 288.

The correct answer is: It doesn't matter. I've never dealt with an equation like this since high school.

(For what it's worth I thought 2 was correct.)

Ah.. Sorry, Mr. West, that is not correct.

You do not need paranthesis around the 2 for order of calculation: A number outside a paranthesis relationship is automatically multiplied against the contents of what's inside the paranthesis before any further calculation (2nd only to processing the internal contents) to come up with the proper quotient, which is 24 in this case.

Three Sources support my answer..:
1) Mathway.com (just checked my facts.., go ahead and try it, under 'Algebra'..)
2) My 'rocket scientist' cousin (more a proud computer geek, actually..)
3) A German Math Ph.d I just emailed (he stayed with my wife and I for a few months here in the States..)

All three answered "2".

Now it's time for suds..!!

Haha! I got a "rocket scientist" (aerospace engineer) cousin also! I sent this to him and he said 2 as well.

High five!

[Brazoo]

Naw it's 2.

Google "PEMDAS" and you will learn again what you forgot
:-)

My cousin said "BEDMAS" which I assume is the same kinda thing.

[david_b]

WOW... I just Googled it..: NEVER heard of that back during high school calculus, but it's works.

Nice way to remember the 'order of operations', Nayrbgo..!!

Math-Geeks Rule.

[Brazoo]

Haha - I asked for more clarity and my cousin just sent me this:

Order of operations - Wikipedia, the free encyclopedia

I think instead of BEDMAS or PEMDAS I'm gong to stick to WOWDIC - which stands for Why Oh Why Did I Care?

Then the answer to every question in the universe must be "Google it"

Although I worked for many years in my chosen field, I do not actually have my degree. Why? I failed algebra nine (yes, you read that right,...nine) times. I would have had to take two out of three of trig, calculus, and statistics in order to graduate. Like that was going to happen. Now, I realize I was a museum worker, but I have not once ever had to use this information. At least during hiring processes, it seemed to be understood that algebra is not needed to teach children about history.
