- diffhist Matrix (mathematics) 20:43 +116 Jacobolus talk contribs (→Matrix multiplication: add a sentence about linear transformations; this is the fundamental feature of matrix multiplication which explains its structure)
- diffhist Matrix (mathematics) 19:54 +1 David Eppstein talk contribs (move sentence about square matrices forming a noncommutative ring from lead to square matrix section; too technical for lead and does not summarize later content)
- diffhist Summation 11:32 +224 Dedhert.Jr talk contribs (move out the history into the notation.)

- diffhist Matrix (mathematics) 03:20 −12 Jacobolus talk contribs (okay, we can use bold as recommended as an alternative by the MOS, instead of a definition list. having these as headings at all is a big distraction, both for the TOC and for the content itself, especially if we add hatnotes for the wikilinks)

- diffhist Matrix (mathematics) 02:03 +27 David Eppstein talk contribs (Undid revision 1292993056 by Jacobolus (talk) this is an accessibility issue; see MOS:FAKEHEADING. The wikilinks in the headings need to go, though.) Tag: Undo
- diffhist Matrix (mathematics) 01:20 −27 Jacobolus talk contribs (Undid revision 1292989484 by Gramix13 (talk) – turning these into headings seems unhelpful. they clutter the contents list and take up a distracting amount of content space for no particular benefit) Tags: Undo Reverted
- diffhist Matrix (mathematics) 00:45 +27 Gramix13 talk contribs (→Addition, scalar multiplication, subtraction and transposition: Gave the operations proper headings.) Tag: Reverted
- diffhist Matrix (mathematics) 00:43 +86 Gramix13 talk contribs (→Addition, scalar multiplication, subtraction and transposition: Added image of matrix addition.)
