WebMar 12, 2024 · Modular arithmetic is sometimes called clock arithmetic, since analog clocks wrap around times past 12, meaning they work on a modulus of 12. If the hour hand of a clock currently points to 8, then in 5 hours it will point to 1. While \(8+5 = 13\), the clock wraps around after 12, so all times can be thought of as modulus 12.
