Errata for 'Algebra: Chapter 0', first (2009) printing

This is the errata for the first (2009) printing of Chapter 0. If you are looking for the errata for the second (2016) printing, click here.

Highlighted in red are the needed changes, embedded in text matching the published version and identified by page and position on the page (e.g., `p.10, top'). A bold reference indicates an error in the published version which may be more confusing, such as a missing hypothesis in an exercise. (My personal favorite is the missing abelian on p.49, Exercise 1.8.)

This list is bound to grow forever. (393 items, and counting.) The contribution of many readers is hereby gratefully acknowledged.
