Thanks again for your help.
No, it has been a long time I left school (I should have probably taken more programming classes though).

Long story short. I have a string like this:
Code:
1+2+1-

Which actually defines 3 numbers (written in the usual format below):
Code:
(+1)
(+2)
(-1)

I am trying to get the result of the sum of these numbers:
(+1) + (+2) + (-1)
Which is equal to:
1+2-1=2

The + or - signs are actually not operators. They tell you if the number before the sign is positive or negative.

Another example:
Code:
10+12-8+4+

Should returns:
Code:
10

Because:
(+10) + (-12) + (+8) + (+4)
= 10 - 12 + 8 + 4
=10

I recognize this format is pretty unusual.
