Unlocking the Secrets of Weekday Calculation: A Simple Mathematical Hack
Understanding time as a cyclical phenomenon allows us to navigate it using a modular number system. For instance, if it’s currently 10 PM and you add 5 hours, the correct result is 3 AM, not 15 PM. Although it may seem confusing, when we reach 12, we reset to zero—a process known in mathematics as modular arithmetic. This concept allows us to express time calculations as 10 + 5 = 3 modulo 12.
Modular arithmetic is not only essential for everyday timekeeping but also has diverse applications, including cryptography and engaging mathematical tricks. This mathematical principle reveals the fascinating interplay between numbers and our perception of time.
