You know, there are some programmers who haven't started with C++ or Java.

Would I?

How would I do that here?

# untested
class FunnyNumber(int):
    """Silly class that acts like an integer, only one larger."""
    def __add__(self, other):
        return int(self)+1+other
    def __mul__(self, other):
        return (self+1)*other
    def __sub__(self, other):
        return int(self)+1-other
