Exploring Discrete Mathematics Using Maple This is a guide to help you explore concepts in discrete mathematics using the computer system Maple. This book can significantly enhance your understanding of discrete mathematics in several ways: providing you with a plethora of interactive examples, making algorithms concrete and understandable by implementing them on your computer, and freeing you to experiment and conjecture without getting bogged down in repetitive calculation. Exploring Discrete Mathematics with Maple is designed to be accessible to those who are complete novices with Maple and with computer programming, but it has much to offer even experts. The introduction explains the fundamentals of how to use Maple and the basics of computer programming with Maple.

The active paths provide the two counterexamples, i.e. Truth values of x, y and z for which the x y z proposition (x → (y ∨ z)) → ((x → y) ∧ (x → z)) is false: T T F.
