These notes were created by a suggestion from Ryan Trelford based on the Fall 2015 offering of Math 135. These were the notes I used in this semester written out completely with commentary. Many pages from this file were given as handouts/displayed on a document camera. I have made note of this by using the heading ``Handout/Document Camera" as used. Please feel free to modify, change, recast, or reproduce these notes in any way you see fit so long as the content continues to help students and be beneficial to learning mathematics. In the header is a toggle for Instructor Comments; these are timing cues and some helpful hints for first time instructors. Special thanks to Alain Gamache and Haochen Yang for catching many of my typos in the early versions of this document.
