• diffhist Elementary algebra 00:44 −52 ~2025-39839-99 talk contribs (I changed from "This use of variables entails use of algebraic notation and an understanding of the general rules of the operations introduced in arithmetic: addition, subtraction, multiplication, division, etc." to "In arithmetic, operations (such as addition and subtraction) can only be performed on numbers. In algebra, operations can be performed on numbers, variables, and terms.") Tag: Disambiguation links added

• diffhist Ordinal number 20:55 +24 Americanastronaut talk contribs (IMO describing this property as "proper subsets are elements" is incredibly misleading/confusing for a casual reader, who is likely to interpret it literally as saying that an arbitrary proper subset of an ordinal must also be an element of that ordinal. In my experience teaching, this kind of elementary confusion is extremely common and great pains should be taken to avoid it whenever possible.)
• diffhist Class (set theory) 20:30 −6 Americanastronaut talk contribs (Just thought of an even better way to word this (esp. since using "subset" here is already kind of self-contradictory))

• diffhist Class (set theory) 20:25 +45 Americanastronaut talk contribs (Edited a paragraph about proper classes as "subsets" of sets in alternative set theories with (hopefully) clearer wording/more encyclopedic tone.)
