You should tell that to Professor Carlos De La Lama

**** Professors like that. They're just pissed because none of their peers think they are as clever as they think they are.

goodlun, you and I were on the same boat on this one. Many thanks for providing a definitive answer, Rabbit.


By the way:

This question is more about how we deal with trolling and nuisances.
Read this page: http://knowyourmeme.com/memes/48293
Then maybe we can start a meta article about identifying and dealing with these threads.
Between the math forums that I moderate and otherwise frequent, and dozens of other forums
(a short list is here: http://www.mymathforum.com/viewtopic...p=79150#p79150),
I'd guess that thousands of hours have been wasted on this garbage.

An A-class trolljob. I took it hook, line and sinker.

Let's all use Reverse Polish notation from now on! Think of all the money we'll save on not building = buttons into our calculators!

The energy savings are pretty good but data center space is EXPENSIVE horizontal racks are not space efficient. You could oil cool them in a Vertical enclosure but that would present some pretty significant problems. Stack them horizontally?

Well here is a reason to get a decent (Top notch) education about computers (not necessarily formal)
Here is the inside of one of Google's data centers, pretty swanky work environment it is fairly similar to the work environment I we had at ATT ENS although ATT was less colorful.

Can you give me a quick algebra tutorial on this? My brain is making the same mistake as that TI 82.

6/2(2+1)

6/2(3)
3(3)

3*3 = 9

What am I missing here? (It looks like you go from 3(3) to 3/3 which tells me there's some principal or basic rule that I've forgotten.)

Sorry if I sound like a dumb ass. Just trying to avoid a slip into early senility and I haven't done any algebra in at least five years.

The problem here is the slash and the way it is taught as a synonym for division and fractions. If this doesn't make sense, I'll add some pictures later. Let me know. If you add two fractions, say 1/2 and 3/4 you end up adding them together like this (2+3)/4.
If you have a horizonal fraction bar the parentheses are implied. Later we learn about the "/" fraction bar and are essentially told it's equivalent to the horizonal bar. Somehow the fact that the implied parentheses don't carry over here gets left out. I know this drove me crazy until someone finally explained it to me a while back, I had definitely learned it the wrong way.

But here's the problem with the parentheses either explicitly added or left off, as it should be since / is equivalent to divsion and not to a fraction bar.

6/[2(2+1] = Six over twice the sum of two plus one.
6/[2(2+1)] = 6/[2(3)] = 6/(2*3) = 6/6 = 1

Six divided by two multiplied by the sum of two plus one.
6/2(2+1) = 6/2(3) = 3(3) = 9

Also, in other news I took the GRE today and by the looks of it I'm going to grad school. Go me.

Also: Holy crap! Where'd those two extra pages come from. Guess that goes in the glitch pile unless you've all been posting non-stop since I started typing. Unless I acidentally left a tab open for days... if so, my bad.
