Applied Mathematical Problem Solving Questions

Focuses on practical mathematical techniques commonly used in cryptography and algorithm design. Topics include modular arithmetic and modular inverse, modular exponentiation, number theory basics such as primes and factorization, bit level operations, computing the greatest common divisor, and working with finite fields. Expect problem solving that tests algorithmic thinking, correctness, efficiency, and the ability to explain mathematical steps clearly. This is not advanced abstract algebra but solid, practical mathematics for engineering problems.
