Big Integer Modular Arithmetic Calculator

The Big Integer Modular Arithmetic Calculator (Big MAC) performs modular arithmetic on very large numbers. An example of a very large number is a googol (1 followed by a hundred zeros).

To use Big MAC, enter a non-zero integer for the modulus m (the default value is a googol), and integers a and b below. Then press one of the operation buttons.

    m =
     a =
     b =
Big MAC hasn't been tested much, so if you have any problems with it, please feel free to send me a message. If you just need to work with ordinary size numbers, the original modular arithmetic calculator should suffice.
