👉 Lightning math is a set of mathematical techniques and notations designed to perform complex calculations extremely quickly, often in milliseconds. It leverages the properties of modular arithmetic and the Chinese Remainder Theorem, among others, to simplify and expedite computations that would otherwise be time-consuming using traditional arithmetic methods. For example, calculating large powers or solving systems of congruences can be done efficiently with lightning math by breaking down the problem into smaller, manageable parts and using precomputed values. This approach is particularly useful in cryptography, coding theory, and other areas requiring rapid computations with large numbers.
