26 May 2022

• 04:3804:38, 26 May 2022 diff hist +21 Log–log plot Revised wording for clarity and changed a link so that it points to a description of power functions, rather than monomials. Rationale for link change: "Power function" refers to the relationship among the variables on both sides of the equation. "Monomial" may refer to only the right side of the equation, it usually implies the exponent is a nonnegative integer, which is not required in this context, and monomials may also contain several independent variables.

• 12:4412:44, 16 April 2022 diff hist +2,697 John Wallis Clarified the discussion of Wallis's conception of negative numbers and their place on the number line, based on additional references. Placed this in its own section. Also added an image (with a caption) of the number line from Wallis's original work.

14 March 2022

• 19:3719:37, 14 March 2022 diff hist −15 m Help:Introduction to editing with Wiki Markup/1 Revised the wording from my earlier edit. This wording is more concise, and it eliminates possible confusion with the previous sentence, which discusses a different kind of reference.
• 16:4916:49, 14 March 2022 diff hist +172 Help:Introduction to editing with Wiki Markup/6 Added bullet to the summary to remind readers of the list of markup rules in the toolbar's Help menu. Also, added closing tags to the list items. current

• 06:1806:18, 22 December 2018 diff hist +7 m Harmonic series (mathematics) →Random harmonic series: "...showed that the convergent is a random variable" ---> "...showed that the convergent series is a random variable" (typo)

8 December 2018

• 20:5520:55, 8 December 2018 diff hist −5 Qualitative theory of differential equations (Relatively minor) Removed "many" due to grammatical error ("information" is an uncountable noun); "much" would work, but it'd be a bit formal.
