## Description

Examines applied, real-world and theoretical mathematical implications of the mathematical concepts elementary logic and set theory, functions, direct proof techniques, contradiction and contraposition, mathematical induction and recursion, elementary combinatorics, basic graph theory, minimal spanning trees. Expands and explores symbolic, numerical, and graphical representations of mathematical concepts. Emphasizes solving problems symbolically, numerically, and graphically and understanding the connections among these methods in interpreting and analyzing results.

## Learning outcomes

1. Apply basic set operations.

2. Negate compound and quantified statements and form contrapositives.

3. Construct a direct proof (from definitions) of simple statements.

4. Apply the Principle of Mathematical Induction.

5. Construct indirect proofs by contraposition and contradiction.

6. Construct explanations for solutions to counting problems.

7. Utilize one or more algorithm for finding a shortest path or a minimal spanning tree in a connected graph.
