Absolutely ... it is quite intriguing.

100000^0 = 1
        10^0 = 1
          1^0 = 1
0.00001^0 = 1
So,     0^0 = 1


0^10 = 0
0^1 = 0
0^0.00000001 = 0
So, 0^0 = 0

As it says in the mathforum article, it depends on which direction you come from!

My humorous professor during college would say that statistically, the result is ½ since we add both results then take the average. That's what he said when he was discussing whether 0 divided by 0 equals 0 or 1.

Ah... So this is the time when you saw Zach's true potential...

I like the questions where we must prove that an equation is always true... Except those which needs many words and theorems, I much prefer the ones where we just need to manipulate the numbers and variables.

"We found the sand was not like the sand in the brochure. Your brochure shows the sand as yellow, but it was white.

This reminds me to when I was still a kindergarten student, I made a drawing of two mountains: One was colored blue, and the other was colored green. When my teacher asked me why one of them was green, I retorted "Have you ever take a vacation? Mountain is green if looked from near. This one is near, the blue one is far".

Hi soroban;

B.O.O.K. is indeed powerful but its enemy Furious Ingestor of Readable Entities(F.I.R.E) and Wetting Agent That Eats Readables (W.A.T.E.R.) are more powerful. Having once had my apartment burned and losing all work, notes, books, magazines and documents, I know what I am talking about. My computer and digital data even though drenched, survived.

This reminds me to what my boss said: We must be careful with fire and water because either of them can ruin or even destroy our products (I work at a book publisher).

I was sitting and thinking (I seen to do that alot. lol) and I had this intresting revalation:

Being in the 7th grade we concide the square root of a negative "undefiend".
Well, I dawned on me that you could just do this: sqrt(-16)=-16^1/2*sqrt(-1)

My math teacher informed me this already existed and they were called imaginary numbers. (I was crushed)

I know how you feel. Back then when I was a 7th grader myself, I realized that if you multiply two numbers whose difference is 2, the result will be the square of the middle number subtracted by 1. When I entered a math major in college I tried to write it down, only to find out that it was (a + 1)(a - 1) = a^2 - 1, an equation already well-known even before I was a 7th grader.

Buzzword bingo is generally played in situations where audience members feel that the speaker is relying too heavily on buzzwords or jargon rather than providing relevant details or clarity. Business meetings led by guest speakers or notable company personalities from higher up the pay scale are often viewed as a good opportunity for buzzword bingo, as the language used by these speakers often includes predictable references to arcane business concepts, which are perfect for use in the creation of buzzword bingo cards.

It's similar to a drinking game, then.

What does the "B.S." stand for? Bovine Secretion?

Homework is independant study and a primer for you to be capable of doing work on your own when you leave school, because you're obviously incapable of doing so without it. It also helps improve your abilities in the language field you are using; which you appear to be having trouble in.

Homework is a good thing and will not be removed from schools or other educational establisments because it mirrors work's reports you'll have to do in a set time frame. If you don't do it, you don't get "detention" or "scolded". No. You get fired.

Nature is large enough to not whine about how we're cutting down trees to make paper out of, so it can get over itself.

I am... genuinely surprised that Zach spilled out some wise words...
