Ok, it is time for Homework - 48÷2(9+3) = ???

[theantiquetiger]

I saw a thread on this in another forum. It is 25 pages long!!!!

The correct answer is 288.

The most common mistake is completing this 2(9+3) before dividing that into 48.

First thing complete this (9+3)

Now the parantheses is complete, the equation looks like 48 divided by 2 times 12

You always go left from right when doing multiplacations and division.

So it is (48/2)x12

Equals 288

I can see why that looks correct, but now I need a math teacher to explain whether and why. I'll be back with an answer next week when we're in session.

Bryan, I got your back....The answer is "2"

[toyman]

The answer is 288,but I am not a math teacher .

[theantiquetiger]

48÷2(9+3)≠48÷(2(9+3))

[theantiquetiger]

Here is the best explanation I have seen:

48÷2(9+3) can be rewritten 48 x .5 x 12

Hey guys,
I just put the equation into Microsoft Excel and the answer came to 288

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

Hey guys,
I just put the equation into Microsoft Excel and the answer came to 288

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

and Bill Gates made $1...

BTW tricky math questions make me angry. You know this equation is set up to make some d-bag feel smarter than everyone else; because most people will do math in the logical way they were taught. This only serves to make someone feel inadequate about their math skills... to me that's just poor.

I ALWAYS LOVED CALCULUS.., and was going for a Math Major in College back in the day.., but Geometry 'proofs' always screwed with my head.

I still use my sliderule, just to be hip around the office.

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.

Ok Superman is flying north at 200 mph and Aquaman is swimming south at 75 mph. How long will it take for Batman to climb up the side of an 80 story building? Please convert your answer to metric.

Hmmm..

It really depends on whether Robin was Jason Todd, Tim Drake, or Dick Grayson..?

[TheDoLittle]

The answer is always 42.

[toys2cool]

48 divided by 2 = 24. 9+3=12
24x12= 288

288 is the answer

yeah that's what I had at first, but these guys confused me with the 2 answer

You ALWAYS do what's in parantheses first..

Always.
Always.
Always.

Yep, Smart AND Sexy..
