Probably a naive question, as math is not my area....but if 0!=1, and 0 to the 0 power = 1, why does 0x0=0? It strikes me that both 0! and 0 to the 0 power can be re-written as 0x0.

00=0^2=0 0^n=0 when n>0 I believe 0! is incorrect since a factorial is for positive integers multiplying up to 1. (i.e. 3!=3x2x1, notice it stops at 1). once again 0^0 != 0^2 (00)

*The reason 0! = 1 is that it is the product of no numbers. The product of no numbers is 1 because that is the multiplicative identity. (1 x = x for all x.)**

0! = 1 because there is a generalization of factorials called the gamma function whereby 0! = gamma(1) = 1. The gamma function is defined as the integral of e^(-t)t^(z-1) dt from 0 to infinity. Integration by parts establishes that gamma(z+1)=z*gamma(z). the gamma function is defined for almost all complex numbers.

Actually, I have a wuestion and I need an answer right away!! Please tell me. Thanks. Suppose you have two numbers. The difference of the two numbers is 12. The product of the two numbers is 17. Multiply the larger of the two numbers by 100, add 50 times the smaller number to that, round the total to the nearest whole number, what is my answer?
