Both output :   2 - 3 + 4   and   2 - (3 + 4)   are correct but the first one is better because "minimize the use of parentheses". It seems to be good.

Update: MeowChow points something right !! I was dreaming when I read his post, forget it :)

Uh, no, addition and subtraction are left-to-right associative, which means that:

2 - 3 + 4 =  -1 + 4 = 3
 while
2 - (3 + 4) = 2 - 7 = -5
