A "gentle" and superbly written introduction to mathematical rigor and proof, this text is designed to prepare students (especially math majors) for subsequent junior/senior-level courses in Abstract Analysis and Algebra by providing extended developments of several basic mathematical topics. It offers a finely-focused, "hands-on" approach to the rigors of mathematical reasoning -- "the mathematical method" -- i.e., developing carefully formulated definitions, clearly stated assumptions, and logically rigorous proofs.
