I think first your main problem is trying to define the problem.  You 
need to define what "nature" you want to read in what circumstances. 
Nobody just reads lines and turns them into strings or ints on a whim.

If you need some definition because your just doing this on your own, 
consider writing a simple parser for algebraic input.  Parsers are 
common in computer science, so they're good to know about, look it up.

The next step is to define some test cases.  Here's some lines you 
should be able to read in and parser correctly.  Note that I'm assuming 
you'll do this "algebraically" and that * and / get evaluated before + 
and -.

1 + 1
-10
1243 + 678 * 5
1 / 3
45 - 34 + 12 - 90 + 78 * 3 / 2
