One could consider xor to be a mathematical operation.

Buy your own chocolate fish...? ;-)

Use a counter of the microcontroller. Step each call, test, reload +
return 1 on over-/underflow. Is this called "outsourcing the heavy
lifting"? The function used to explain the algorithm would be easier
though. Or are we dealing with one of these retarded microchip 3bit CPUs
here? *ducks for cover*

  static unsigned counter = 0;
