Could you use words (eg tex) instead of symbols? They don't translate.
I assume the left-hand side is
1*1! + 2*2! + ... + n*n!
The right-hand side involves (n+1)! but I can't guess what it is.

Prove that 1*1! + 2*2! + ⦠+ n*n! = (n+1)! â 1 whenever n is a positive
integer.
I know I should use induction to prove this... but how?
