What does 5! Mean in math a?
It means "5 factorial"
which means, 5x4x3x2x1
(= 20x3x2x1= 60x2x1 = 120.)
(the number times every other number it takes to get to 1).
For example, 9! would mean 9x8x7x6x5x4x3x2x1
yeah...what she said!
( there is usually a function on your ti-86 calculator that will compute this.
yuppp its what Editor said :] you can do that to any number except for one or zero
