Learning Hours: 120 (36L;36Lb;48P)

One-Way Exclusion: May not be taken with or after CISC 203/3.0.

This course is a direct prerequisite to

  • CISC-203/3.0 (Discrete Mathematics for Computing II)
  • CISC-204/3.0 (Logic in Computing)

and a co- or pre-requisite to CISC-121/3.0. This course is required in all Computing programs except COMA.

Introduction to Mathematical Discourse (2 weeks)
  • propositions and connectives
  • terminology: hypothesis, conclusion, converse, contrapositive
  • quantifiers and predicates
  • logical implications and equivalences
Sets (2 weeks)
  • sets and subsets
  • set operations and the laws of set theory
  • counting and Venn diagrams
  • countable and uncountable sets, orders of infinity
Integers and Induction (3 weeks)
  • well-ordering
  • recursive definitions
  • the division algorithm
  • the Euclidean GCD algorithm
  • the Fundamental Theorem of Arithmetic
Functions (2 weeks)
  • Cartesian products and relations
  • functions: 1-to-1 and onto, bijections
  • inverses and composition
Relations (2 weeks)
  • equivalence relations and partitions
  • linear and partial orderings
