Question

10*9*8*7*6*5*4*3*2*1 = 10!
Can this be true?! Why or why not?

Answer 1

yes.. as this is a relation

Answer 2

I agree that this is true because 10! (which is 10 factorial) means:
10*9*8*7*6*5*4*3*2*1

In other words, 10! is the shortened way of writing this string of numbers. This is true of any factorial, e.g., 7!=7*6*5*4*3*2*1
