These are notes from a first term abstract algebra course, an introduction to groups, rings, and fields. There is an emphasis on specific examples.
I hope to revise these notes at some point, and also get notes for additional topics in abstract algebra written up. There's a need for more motivation, and more pictures.
The first link in each item is to a Web page; the second is to a PDF (Adobe Acrobat) file. Use the PDF if you want to print it.
[July 29, 2022] I corrected typos and made some minor cosmetic changes to the notes on groups and rings.
