## technopanda13 2 years ago how do factorals work?

1. tcarroll010

In an introductory treatment of factorials, a positive integer is represented with an exclamation point after it. Factorials are not limited to integers, but unless you are considering advanced concepts of factorials, you will not have to concern yourself with non-integer factorial for quite a while. So, stick to positive integers for now. For any positive integer, it would be that integer times the next smaller integer times the next smaller integer from that and so on until you get to one: n! = (n)(n - 1)(n - 2)(n - 3) . . . (3)(2)(1) so, 5! = 5 x 4 x 3 x 2 x 1

All good now, @technopanda13 ?

3. technopanda13

yes thank you could you help me with one more thing?

4. tcarroll010

you're welcome. Sure, I can help with another question.

what is BxH^2 for?

6. tcarroll010

Is this in regard to some formula for something or in regard to some geometric figure? Are you sure you don't mean: A = BxH/2 ? Because that is the formula for the area of a triangle.

The only difference is in the "^" and the "/"
