simple: compute the next factorial after the last one in this thread
i start at 1!=1, the person below me computes 2!, the next one after that does 3! and so on
in forum games
factorial
2!=1+2=3
factorials, not triangular numbers
2! 1*2=2
oh ye sorry.
3! 123=6
4!=1×2×3×4=24
5! = 1x2x3x4x5 = 120
6!=1x2x3x4x5x6=720
Didn't say you had to write out the equation but ok
7! = 5040
8! = 40,320
9!=362,880
10! = 3,628,800
11! = 39,916,800 = 3.99168e7
12! = 479,001,600 = 4.79e8
13! = 6,227,020,800 = 6.22e9
14! = 87,178,291,200 = 8.7178e10
15!=1.3076744e+12
2.092278988800*10^13, or 2.092278988800e13
