Basic Factorial from 1-10

Hello all...I'm new here and I've searched some old posts for what I'm looking for, but haven't quite found it. I'm doing some tutorials in a book I've got and at the end, I need to complete some exercises. Given the fact that I've just completed the LOOPS chapter, I know that the factorial exercise I need to complete must involve a loop.

The problem I'm having is creating the formula for the factorial. Basically, I want to print two columns displaying numbers of 1-10 in one column, and the factorial for each number in the other. I've got the column printing and incrementing of numbers down. I just need to get the appropriate calculation.

I don't want to use the factorial function because I haven't learned about that yet and I just want to do the basic calculation for the factorial in a loop.

Can someone please help? Thanks!!
