A small funny game.

It is known, operator '+' means addition. And expression "1 + 1 = 2" is always right. But if we redefine operator '+',make it means subtraction. Then, the expression "1 + 1 = 2" is wrong, the result should be '0'.
This game,by redefining all the arithmetic operators,enhance your thinking skills and bring you fun.
