exponential modulus

Exponential modulus is a concept in mathematics where you compute a large number raised to a power and then find the remainder when dividing by another number. For example, "a^b mod n" means you multiply "a" by itself "b" times, then divide the result by "n" and take the leftover part (remainder). This technique helps perform calculations with very large numbers efficiently and is essential in areas like cryptography, ensuring secure communication. It combines exponentiation with modular arithmetic to keep numbers manageable and meaningful within a specific range.
