##### Supplemental Materials by Chapter

Slide Shows are PowerPoint files offering additional explanation of key concepts in the book; Podcasts of those same Slide Shows are MP4 video files with accompanying narration by the author. Spreadsheet Templates are Excel files that provide basic instruction in the use of spreadsheets as well as prepopulated formulas that can be used to perform various calculations described in the book; Spreadsheet Podcast Demonstrations are MP4 video files of those spreadsheets with accompanying narration by the author. Appendix files provide supplemental textual material in PDF format.
