Math Factorials

Fri Jun 23, 2006 1:34 pm

How do you add and subtract factorials?
Is it like this?
2! + 3!= 2+6?
5!-2!=120-2?

Actually 2! is 2*1=2 and 3! is 3*2*1=6
And 5! = 5*4*3*2*1 = 120. You were right mvpshaq32

You doing this still? this is jsut the easy one, the
hard ones is ones like 236572C2 but o well
basically what Jing said is correct but its multiply not add the factorial 2! 2*1 2+3! 2+(3*2*1)=8 =2+6 but you got it good job (Y) lol

Alright thank you.
I was in tutoring and they were talking about factorials and I was playing my friends Gameboy SP so I didn't hear anything they said. I never learned factorials before so I just wondered.
