I'm a mechanical engineering student too.
You can use eActivity to do some calculation and iterative operation it's like doing in Main.

How about actually answer his question?

If you want to enter numbers from n numbers and store them, I'd suggesting using this way:

{}=>x
Input n
For 1=>i To n
Input x[i]
Next

Instead of having values from x1 to xn, it creates a list of values. Basically, that's what you want to do, and it's the best way to do it.

If you want some nicer text in the input boxes, you can also do this:

{}=>x
Input n,"Number of values:"
For 1=>i To n
ExpToStr i,s
StrJoin "x",s,s
StrJoin s,"=",s
Input x[i],s
Next

Also, I seriously hope you're not English, check your grammar, it's just horrible to read.
