Your class is missing a closing bracket.

EDIT: Put it at Line 54 if you don't see it. Don't forget the semicolon afterward.

Don't forget to add a semicolon after the closing bracket for your class as well.

Also, your subtraction function is wrong.

after adding the semicolon and brackets and all it still has a compilation error.
