Numbers cycle like clocks in modular arithmetic
Modular arithmetic makes numbers cycle like a clock, simplifying complex calculations and enabling everything from secure data to repeating days of the week.
Modular arithmetic, often called 'clock arithmetic,' makes numbers cycle back to zero after reaching a specific value. Imagine a 12-hour clock: 12 + 1 equals 1, not 13. This system, formalized by Carl Friedrich Gauss in 1801, simplifies complex problems by reducing large numbers to manageable remainders.
