This is the background reading supplement for Introduction to Mathematical Thinking course by Coursera (https://www.coursera.org/course/matht...).

Quoting from the document
"NOTE: This course reading is abridged from the course textbook, Introduction to Mathematical Thinking, by me (Keith
Devlin), available from Amazon as a low-cost, print-on-demand book. You don’t need to purchase the book to complete the
course, but I know many students like to have a complete textbook. In developing this course, I first wrote the textbook,
and then used it to construct all the course materials.
