Can we continue the thread here?

Anyway, 100! equals

9.332622e157.

What is e?

Speaking of e... I got E on GeoGebra, I zoomed out and it ended up with 6.5E9. I know thats greater than 1,000,000 units, because I passed that.

e or E in this case stands for exponent. If you say

5.3434 e4 that means 5.3434 x 10^4

9.332622e157 that means 9.332622 x 10^157

6.5E9 that means 6.5 x 10^9

6.5E9 = 6.5 x 10^9 = 6 500 000 000, I do not know how you are getting 20,711,912.8

I figured that 100! is somewhere around...

654,747,700,701,377,386,126,856,657,861,679,570,529,800,895,801,424,573,182,559,133,258,946,484,061,065,580,876,771,978,236,269,380,302,819,031,314,362,546,968,961,704,181,923,607,153,180,171,236,969. That's QUINDECILLIONS!

Speaking of infinity, I think 0^0= -0, which is infinity... for it is beyond definition....

GeoGebra said it was infinity too.

I scrolled over and i found a maximum of 10E19.

It is not a theory since you didn't show any arguments that it should be so...

No, it is not. -0 is equal to 0.

0 is neither -0 or +0.

If you mean to say that zero is neither positive nor negative, you're absolutely correct. But '-0' isn't the same as saying 'zero is negative'!

To see why 0 is the same as -0 *and* +0, imagine +1, +2, and so on, as a line starting from zero, like this:

A negative number is the same as a positive number, except you reverse the line. It's Stays the same length and still starts at zero, but it's flipped. For example, -2 looks like this:

You can imagine "flipping the line" with numbers closer and closer to zero (shorter and shorter lines). But what happens when your line gets so short that it doesn't really have length? (You could say "0 length").

By that stage, you don't really have a line anymore. You have a *point* which represents zero:

Because it doesn't have any length "flipping" it doesn't change it, so +0 is the same as -0.

Hi;

Please follow the other thread. There you will find good reasons for 0^0 = 1.
