👉 Seconds math, also known as time arithmetic, is a system for performing mathematical operations involving time, such as addition, subtraction, multiplication, and division, where the units are seconds. Unlike standard arithmetic that uses whole numbers for quantities like money or distance, seconds math uses fractions of a second (like milliseconds) to represent time intervals. For example, adding 500 seconds to 1 minute results in 61 minutes and 40 seconds (since 500 seconds = 8 minutes and 20 seconds). This system is particularly useful in contexts like sports timing, scientific experiments, or any scenario where precise measurement of time intervals is crucial.
