Limits are a calculus/Geometry concept. A special case are Cauchy-sequences which model approximations.

Domains (as I know the term) are more of a set theory idea. Not that that matters.

Algebra also seems to be part of thinking well, however, calculus exposed me to patterns that I hadn’t seen in programming all that much. Many of the Algebra patterns I had already been familiar with from programming.
