Student Learning Outcomes
- Students will apply number theory, combinatorics, discrete probability, graph theory, and recursion to solve various application problems.
- Students will develop conceptual understanding of formal logic and various methods of arguments that can be used as the basis of a computer program. They will demonstrate and communicate this understanding by writing proofs involving number theory, set theory, combinatorics, and discrete probability.
