Question

what is factorial in math​

Answer 1

Step-by-step explanation:

the factorial n, written as n! is represents the product of all integers from 1 to n both inclusive

for example 6! = 6*5*4*3*2*1 = 720

                    5! = 5*4*3*2*1 = 120

you cannot add or subtract like this  6! - 5! =1!

but you can divide like this 6! / 5! = 6*5! /5!

so 5! cancle each and the answer is 6
