how do you solve this 7!-5!?

Question

its has to do with permutations.

Answer 1

! means factorial and is equal to n*(n-1)*(n-2)....*3*2*1

so 7! = 7*6*5*4*3*2*1 and 5! = 5*4*3*2*1

then 7! = 5040 and 5! = 120

5040 - 120 = 4920

Answer 2

7!-5!

7!= 7*6*5*4*3*2*1 and that equals 5040 and 5!= 5*4*3*2*1and that equals 120 so

5040-120= 4920

so the answer is 4,920.
