Evaluate the following expression
13!
Factorial Definition
Product of positive integers ≤ n.
n! = n x (n - 1) x (n - 2) x ... x 2 x 1
Factorial Expansions are as follows:
13! = 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
13! = 6227020800
Simplify factorial expansions:
13! = 6227020800
Excel or Google Sheets formula:
Excel or Google Sheets formula:=FACT(13)What is the Answer?
