- Propositional logic and predicate logic.
- Techniques of mathematical proofs including direct, indirect, and contradiction proofs.
3. Combinatorics
- Permutations and combinations.
- The principle of inclusion-exclusion and applications.
4. Graph Theory
- Definitions related to graphs, such as vertices, edges, paths, and cycles.
- Types of graphs including directed, undirected, weighted, and bipartite graphs.
5. Algorithms and Complexity
- Basic algorithm analysis and complexity classes.
- Introduction to recursion and its applications.
6. Number Theory
