I'm sorry I don't see your point... Division is a non-commutative operation (x/y != y/x). I am trying to gauge people's interpretation of implied multiplication operators. If we solve for the general case, the specific case in the other thread should follow QED.

Sorry, first we establish that x/(yz) = (xy)/z does not hold true for all values of x, y and z.

http://www.wolframalpha.com/input/?i=(x ... +x%2F(y*z)

Then, given x/yz, we evaluate both multiplication and division at the same priority, left to right. Meaning x/yz = (x/y)z.

Could you elaborate further, the example from the link you posted is : (x/y)*z = x/(y*z) . I do not see any implied multiplication in that example so it does not support the example in your last sentence. Maybe I am missing something?

Man, them brackets come in SOOOOO handy at a time like this.

If someone went for a thesis using this notation, they'd get a big, glaring...

(Yeah, I'm still bummed I got fooled on the other equation. :? )

Blah blah blah....

NO mathematician worth his SALT would write an equitation that way. Mathematics as all about being anally retentively precise. It would and should be written with proper bracketing to ensure that you get the answer that you desire. If I saw this on an exam by a student... WRONG it is too ambiguous do it again.

May I suggest this thread be locked? The first poll was good, the second one was funny, but what's the point anymore?

Or may I suggest you grow a pair and show some self restraint by not reading the threads that bother you, instead of suggesting the imposition of censorship upon others who may think a thread valid. Suck it up buttercup!!!!!!! and don't be a social/thread nazi!!! BTW this was the second thread. :smt075

You stand corrected.
This was the first thread: viewtopic.php?f=49&t=72928
This was the second thread: viewtopic.php?f=49&t=72960
Now THIS is the third thread on the topic of convoluted and ambiguous simple math problems...

On a related note, may I suggest you grow a pair and show some self restraint by not reading my posts that bother you. You don't need to complain about my complaints.

I had better chances of you responding, to a thread you thought should be locked, if I made an error tauntingly worthy of reply after my provocative post.

I don't have a problem with people complaining/debating, I don't like social/thread nazi's calling for censorship because they don't like what is being said. If you cannot cope with what is being said in a thread do not read it and move on to the next. This is not high school, its the Internet. We have too much censorship on this site already.
