Find the missing number || Puzzle 4

It doesn’t matter about the sign between the two numbers,

The next puzzle will be posted after solving this…

I guess the missing number is : 22

Yeah, 22 is correct.

But can you please explain why?

22
It’s all about factorials

6!-5!=600
5!-2!=118
8!-7!=35280
Same as,4!-2!=22
