Prime Numbers and Sieve

This is a basic level class where we will be discussing about prime numbers and standard primality tests. We will also be discussing the sieve of Eratosthenes and some basic problems on them. This will help learners develop some basic understanding and logic in number theory.

Segmented Sieve and Divisors

This is an intermediate level class where we will be discussing a variation of sieve known as segmented sieve. We will also be covering some problems involving counting divisors, sum of divisors etc. which are seen quite often in competitions and interview rounds as well.

Combinatorics with Number Theory

In this class, we will be discussing some problems that involve some combinatorics and some number theory concepts taught earlier like primes, divisors, sieve etc. These kinds of problems are seen a lot and getting the hang of some basic ones can be helpful in solving similar problems later.
