👉 Witch math, also known as hexadecimal or base-16 arithmetic, is a system of numeration that uses sixteen distinct symbols: the digits 0 through 9 and the letters A through F, where A represents 10, B represents 11, and so on up to F representing 15. This system is particularly useful in computing and digital systems because it aligns well with binary (base-2) systems, which are fundamental in computer science. In witch math, operations like addition and subtraction are performed differently than in decimal (base-10) arithmetic, often involving the carrying of values to the next place value and using modulo 16 to handle overflow, making it a compact and efficient way to perform calculations in digital contexts.
