On the Subject of Modulo

For those wanting a crash course on the modulo operation, fill yer boots!

  • The module shows two numbers and a keypad.
  • Take the larger central number (n) modulo the smaller number in the corner (m).
  • To perform the modulo operation, subtract m from n until n < m. Whatever you have left is the correct answer.
  • Alternatively, divide n by m and take the remainder.
  • Whichever method you prefer to use, once you have calculated the correct answer, enter it into the keypad and press the green submit button.
  • To clear your answer, press the red clear button.
  • Entering the correct answer will disarm the module. Entering an incorrect answer will cause a strike and reset both m and n.
