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

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