Understanding Clock Arithmetic Modulo
Clock arithmetic modulo is a system of arithmetic for integers, where numbers "wrap around" upon reaching a certain value, the modulus. Think of a clock: after 12 o'clock, it wraps back to 1. In modulo arithmetic, we are only concerned with the remainder when a number is divided by the modulus. For example, in a 12-hour clock (modulo 12), 15 hours after 10 o'clock is 1 o'clock because 15 mod 12 = 3, and 10 + 3 = 13 which wraps to 1 in modulo 12. This tool helps you visualize and calculate time in different clock formats using this concept.
