To Plug, or Not to Plug

This page is a collection of ideas, advice, and good problem solving principles gleaned from my own personal study of mathematics and teaching experience. It is not intended to be scholarly, exhaustive, or in any way super elegant, merely a group of items that I wish to put in one place so that I can refer students to a written reference. If it serves as a help to them in even a minor way, it will have been worth the trouble to provide it here. Check back from time to time, in case I add items in the future. Thanks.

Always use small numbers whenever possible.
