Few questions about Zero:

1) What is 0! (1?)
2) What is 0^0 (non-existent?)
3) Is Zero positive, negative or neither (I would guess that last choice)

Yes 0! = 1
0^0 is cannot be determined.
Zero is neither positive nor negative

A few more: (Disclaimer: Use these @your own risk. :wink: These are based on what I found from the web)
Zero is even
For any integer k, k^0 = 1
Zero is divisible by every integer (except 0), Since remainder of 0/k = 0
Zero is a multiple of every integer. 0 = k*0

One reason why 0^0 is not determinable could be explained in this fashion -
0^0 = 0^x/0^x (x not equal to 0) = 0/0 (which is indeterminable).

1) What is 0! == 1
2) What is 0^0 == 1
3) Is Zero positive, negative or neither = Its NEITHER!

Its is determinable!! Try entering it in a scientific calculator (windows calculator has scientific mode) you will get 1!

And, yeah ur logic is correct!

The scientific calculators that I had, when I was a child, did not give 1!!!

Can somebody explain this?
Zero is divisible by every integer (except 0), Since remainder of 0/k = 0

Suppose 0/2
Quotient 0 and reminder 2.
Is this right?

Nayan, in division,

Number = Divisor * Quotient + Remainder

In case of 0/2, Number = 0, Divisor = 2.
Since 0 = 2*0 + 0, we have Quotient = 0 and Remainder = 0.

Does that help?

0^0 is 1 because, any number to the power 0 is always 1.

For example 2^0 = 1; -1^0 = 1; So is 0^0 = 1

Any number (excluding 0) has n^0 = 1 for this reason:
(its not an axiom, its a provable theorem).

n^2 = n^3/n
n^1 = n^2/n
n^0 = n^1/n = n/n = 1.

So 5^0 = 5/5 = 1.

0^0 is undefined.

1) 0! = 1.
2) 0^0 --> I think it's undefined.
3) Zero is neither positive nor negative.
