it's 2, not 288! gee, your friend sucks at math!
if no multiply sign, in this case, 2(9+3), everything that attaches to the bracket has the highest precedence!
And also, multiplication has the highest precedence than division!
Check your school math books!
Did you read what I write? When it comes to multiplication and division, it's very important to specify which one they wanna do first because the result when you do it in the order as described is not exactly identical of the other way around. Practise more and you'll know!
I wonder if you ever take computer science courses. :rolleyes:
Debate? Sounds like you are more interested in insulting people who have the right answer.

This is the reason why we are debating! What is this person's point of view?
There is NO debate.. The person who wrote the equation knew that the answer is 288. Like Chef said, if he wanted the answer to be 2, then the equation would have been written a different way. As it stands, the way it is written, 299 is the only correct answer. People who answer 2, need to stop over analyzing and take the question as it is.

While we are on the topic of mathematics, could someone please evaluate this infinite series:

1 + 1/2x2 + 1/3x3 + 1/4x4 + 1/5x5 + 1/kxk... Does it diverge or converge, and if indeed it converges, what does it converge to?

should check math book. i forgot since 2nd year uni math! haha!

I interpret it to mean 1 + 1/2x2 + 1/3x3 + 1/4x4 + 1/5x5 + 1/kxk... = 1+ 2/2 + 3/3 + 4/4 + n/n... = 1+1+1+1+1+1... = infinite.

(Assuming that you mean that k = series of numbers = 1, 2, 3 ---> infinity)...as k approaches infinity, 1/kxk approaches 0. The sum of the series as k approaches infinity will be 1.645 (rounded)

There is no debate. You're simply wrong and point of view will have no bearing on the solution of this very basic problem.

Why don't you go by the closest university and see if you can pester a math prof to solve this basic question for you. Then when he demonstrates to you that you're an idiot you're going to feel like a real asshat for insulting the people on this thread who know how stupid you look.

Let me remind you guys about an elementary school math memory tool:

BEDMAS
Brackets
Exponents
Division
Multiplication
Addition
Subtraction

48/2*(9+3) first the brackets
48/2*12 then the division
24*12 then the multiplication
288

For my next trick I will attempt to prove 1=0.

And I will prove how the diagonal of a unit square is 1. :cool:

JUST like in real-life; it all depends on your PERSPECTIVE...

$2 per hour is better than $288, if you are the payer...
$288/hr is better than $2, if you are being PAID...

BUT in this case, the answer is 288, no debate...

This is a very interesting response. I applaud you for such a reasoned approach. I like the way you think. Please take your answer and multiply it by six, then take the square root of the product and see if that turns up anything interesting. Restate your answer accordingly.

it seems like you don't think of how others interpret this equation, huggzy. ;)
Simple! Bad way to present this equation!
There is no other way to "interpret" this equation. It is the way it is. If you interpret it the way you are, then you're interpreting it incorrectly. The order of operations is not subject to interpretation and the equation is not a bad way to present it - unless the writer of the equation did not intend to have an answer of 288.

The answer is 3.1415....

The interesting part of your puzzle is that the exact answer you're probably seeking is pi.

I believe the formula you posted is the Riemann Zeta Function and pi squared/2 is the exact value of the Riemann Zeta Function of 2 (yes...I read wikipedia really well!)

Huggzy is 100% correct.

i think this is what some people interpret! nice logic! and yes there are many ways to interpret 2(9+3)!
No, there isn't.

The operation 48/2 MUST BE COMPLETED FIRST. ORDER OF OPERATIONS. PERIOD.

48/2(9+3)=24(9+3)=(216+72)=288

END OF STORY. YOU ARE WRONG.
