Definition of a factorial

A factorial is represented by the ! symbol. It's essentially an operator that means to multiply the term before it by every positive integer less than itself down to 1. So 2! is 2*1 is 2, 3! is 3*2*1 is 6, 4! is 4*3*2*1 is 24, and so on. You cannot use factorials on negative numbers (as proven below by attempting to plug in 0 to n). It's used a lot in series.

Despite what you would logically think, 0! does have an answer.
n! = n(n - 1)!
   i.e. 4!  =  4*3*2*1  =  24  =  4*(3*2*1)  =  4(3!)

n! / n = (n - 1)!

set n = 1
1!/1 = (1-1)!
1/1 = 0!
0! = 1

Defying logic with proofs.

By the way, Mashi, a probability of .102 is a percent chance of 10.2. So you may or may not have failed math there.

I'm actually closely reading all this shiz in attempt to reprogram my brain for school, since the "logical thinking" portion has been turned off for upwards of 3 1/2 months.

And Mashi, learn how decimals work.

[FireArrow]

20 - 1 = 20
20 - 1 = 19

Both are true.

Riddles and logic puzzles on smartphones/tablets. They do more than you'll notice.
