Description This flowchart answers the question "How do you draw a flowchart to calculate N factorial?" N factorial is represented as N! where the exclamation point means factorial. For example,

1! = 1

2! = 1*2 = 2

3! = 1*2*3 = 6

4! = 1*2*3*4 = 24

...

N! = 1*2*3...*N

The next question might be "Can you find a function that computes N! from N without doing each multiplication?"
