Hi Everybody!

I need to develop a basic calculator with only the basic functionalities i.e +,-,*,/ in java for my University assignment.

The restriction is that the calculator must be programmed without using any control statement e.g if, else, or any loop or switch statement.

But the problem is that the range of this number is so long and greater than the ranges of data types like int, double or float. Please tell me the method how to add these two numbers.
