Last Monday the teacher explained to us the concept of “factorial”. I don’t get it.

Simply stated, the factorial of ANY given integer is simply the product of all its prior integers starting with 1 leading up to AND including the given integer itself. Examples…. 3!=1x2x3 6!=1x2x3x4x5x6

As you have just started factorials, I believe you only need to know about the factorials of positive integers. The factorial of a positive integer is all the integers from 1 all the way to that integer inclusive multiplied together. So n! = 1*2*3*…*n.
