Proofs and Concepts: the fundamentals of abstract mathematics by Dave Witte Morris, Joy Morris
Publisher: University of Lethbridge 2009
Number of pages: 220
This free undergraduate textbook provides an introduction to proofs, logic, sets, functions, and other fundamental topics of abstract mathematics. It is designed to be the textbook for a bridge course that introduces undergraduates to abstract mathematics, but it is also suitable for independent study by undergraduates (or mathematically mature high-school students), or for use as a very inexpensive supplement to undergraduate courses in any field of abstract mathematics.
