- diffhist Mathematics 04:26 −14 Finitefields talk contribs (Undid revision 1290945479 by Finitefields (talk). Referring to algebra as the art/study of manipulating formulas is used multiple times in the page, so I'm undoing and moving the discussion to the talk page.) Tag: Undo
- diffhist Mathematics 02:58 +14 Finitefields talk contribs ("The study of formulas and related structures" is a misrepresentation of algebra. The Wikipedia page for algebra itself does not use the word formula until paragraph 18.) Tags: Reverted Visual edit

- diffhist Graph (discrete mathematics) 04:30 −34 David Eppstein talk contribs (Undid revision 1290491005 by Manitofigh (talk) ordered and unordered pairs are a way of representing edges with directions. They are not the only way. For instance, representing a graph as a set of pairs works very badly for mixed graphs and multigraphs and is somewhat cumbersome for graph orientations. for We should keep representation details separate from the basic idea of a graph.)

- diffhist Decision problem 00:02 −34 Nyngwang talk contribs (wording: an example of "decision problem" is just about the problem itself; requiring "an existing algorithm" is misleading.)
