Chapter numbers correspond to “Elements of Mathematical Reasoning”, Third Custom Edition for Illinois State University, published by Pearson Custom Publishing. ISBN: 0-536-18515-8

Note: This custom edition is divided into two main sections, so there are some chapter number duplications. Section 1 uses letters to identify subchapters (like 4D), while Section 2 uses numbers (like 4.3).

Reasoning (inductive and deductive), argumentation, logic, truth tables, Venn diagrams.
