It is correct because the statement is: A + (-B) = 50 -25 = 25

I haven't checked your entire code because you have fundamental
misunderstanding how basic mathematics work. If you balance out your
pluses and minuses you will find that most compilers will follow the
basic maths rule.

The left to right parsing applies when there is equal precedence: ( * /
) or ( + - ). Multiplication/Division takes priority AFTER
(brackets) followed by pluses and minuses.

Brackets, Division, Multiplication Addition Subtraction.

In future please post a more realistic example rather than posting a
statement full of {+++----******///////}. It's just plain silly because
nobody will ever encounter such things in practical situation.

Recently I have seen many time wasters here posting useless examples and
people are wasting time reading them.

Sorry. I just realized this sentance makes no sense :) -- Ian Main
