Why does zero factorial (0!) equal one (1)?
Why does factorial zero (0!) is equal to one?
How many zeroes are in 100 factorial? What is the factorial of 1? How do we find the number of trailing zeros at the end of a factorial? How do I calculate the number of zeroes in N! * M!? (N factorial * M factorial)? Why are they zeros? Is zero a rational or irrational number? What is a factorial? 1! +2! ^2+3! ^3…+100! ^100 no of zeroes at the end? How can we factorize x^3-x^2-1=0? Does [math]-1[/math] factorial, [math](-1)![/math], exist? Is zero an even number? What is the importance of zero? A few zeros means? Is 0/0 zero or infinity? And why? Why is 1+1 equal to 2 but not 11? What is [math]0^0[/math] (the zeroth power of zero)? What is the exact definition of a factorial? Why is 'zero divided by zero' is not defined? How can I factor x^10+x^5+1? What is the difference between 0^0 and 0^1? Why some people use not instead of zero? Is zero a positive integer? Are factor pairs of a given number ALWAYS two integers that are factors of that given number? Is zero an integer? What is importance of zero? What is 0/0? Is it one, zero or infinity? What does 1/0 multiplied by 0/1 equal? Why is value of anything power 0 is 1.. i.e. x^0=1? What is {0} +1? Is this an acceptable factorization of [math] \frac{2}{3}b^5-\frac{1}{6}b^3+\frac{4}{9}b^2-1[/math]? Why or why not?
