Yes, I would agree.
. . . . .add category: probability / statistics
. . . . .add category: arithmetic (that is, K-through-pre-pre-algebra)
. . . . .add category: recreational (not a general-chat "lounge", but
. . . . . . . . . .. . . . . . .interesting math-y stuff, like research results,
. . . . . . . . . .. . . . . . .topic-specific reference sites, "Pi Day", etc.)
. . . . .add to category: diff-EQ to "Calculus"
. . . . .add to category: pre-algebra to "Beginning Algebra"
. . . . .change category: "Other" to "Advanced" (specifically, post-diff-EQ)
Right now, "Other" is taking both third-grade arithmetic and graduate-school complex analysis. These areas could usefully be split, I think. And right now math jokes and interesting articles on new research results have no place to go.
Just an idea....
