Insert mathematical operators to make it true like factorial, root,percentage,addition,multiplication etc​

Answer 1

Answer:

Step-by-step explanation:

Is there a notation for addition form of factorial?

5!=5×4×3×2×1

That's pretty obvious. But I'm wondering what I'd need to use to describe

5+4+3+2+1

like the factorial 5! way.

EDIT: I know about the formula. I want to know if there's a short notation.
