Hi MamaBee;
Sometimes I use a computer to solve them but mostly a lot of trial and error. There are some hints from the problem:
1) S + L must be less than 10 because there is no carry in the next coulumn.
2) If P + N is less than 10 then E must be even.
3) C is not a 0 because they rarely if ever use a leading digit of 0
4) Neither P or N is a 0 because N + P = N or N + P = P

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
