10!

10! (10 factorial) is the product of all positive integers from 1 to 10:

10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

Calculating this:

10 × 9 = 90
90 × 8 = 720
720 × 7 = 5,040
5,040 × 6 = 30,240
30,240 × 5 = 151,200
151,200 × 4 = 604,800
604,800 × 3 = 1,814,400
1,814,400 × 2 = 3,628,800
3,628,800 × 1 = 3,628,800

Answer: 10! = 3,628,800
