Use 3 "3"s to get to 20 (not restricted to the 4 elementary arithmetic operations)

PXS,
Would you please be so kind to translate this formula into "English" for we non-math majors? Thanks.

The '!' symbol (pronounced factorial) means "multiply together all the numbers from 1 to x"
So - 5! is 5x4x3x2x1
So - 3! is 3x2x1 which is 6
and 3!! is 6!
