You have to subtract right minus left in both cases. Also, you don't have to use abs(); 16 - 42 should give you a negative number, so that it will be subtracted from the hours. (Adding a negative number is the same as subtracting a positive number; this is called "algebraic addition".)
So, for your example, your expression should simply be:
? ((12-7)*60)+(16-42)
Some parentheses are unnecessary for the calculation, although they may help for clarity. Anyway, your expression might also be:
? (12-7)*60 + 16-42
