You have the value of x and you know that 30 is a number literal.
You could "assume" that + is the addition operation, because 30 is a 
number and x is of type int.

Then the value of parent.leftPadding is (x - 30).
No need to actually evaluate it.

I don't see a general solution for things like this though. Handling 
those cases would be a huge bouquet of special cases.
