Hi guys, I'm not getting the idea the superposition method in math, I mean if I have X then by superposition I can do X=x1+x2+x3+x4+x5+x6+x7+x8.....+xn
but why?! thanks. I'm not understanding the concept of superposition ..

I have no clue what you are talking about. You need to give a problem completely and exactly or, even better, give the definition of "superposition" used in your book.

What course did this come up in?

Are you by any chance talking about

\(\displaystyle \displaystyle X = \sum_{j=1}^n x_j.\)
