For the last six months or so I have been systematically going through the abstractmath.org files, editing them for consistency, updating them, and in some cases making major revisions.

In the past I have usually posted revised articles here on Gyre&Gimble, but WordPress makes it difficult to simply paste the HTML into the WP editor, because the editor modifies the HTML and does things such as recognizing line breaks and extra spaces which an HTML interpreters is supposed to ignore.

Here are two lists of articles that I have revised, with links.

Major revisions

• Introduction to Abstractmath.org
• Functions: Images and Metaphors
• Mathematical Structures
• More about the Languages of Math

Other revised articles

• Conditional Assertions (if-then statements).
• Definitions
• Dysfunctional Attitudes and Behaviors
• Existence Assertions
• Mathematical English
• Specification and Definition of Function
• Variable Objects

Other recent changes

• Mathematica Notebooks. This gives access to the Mathematica Notebooks and CDF files used in all the abstractmath.org documents and in Gyre&Gimble posts, as well as many of the graphic illustrations used in those files.

• A list of expository articles and class notes.
