The definitions that were on this page are now on three pages:
- Sets: sets, subsets, unions, intersections, complements, Cartesian products, and the extended non-negative real numbers.
- Functions: functions with their domains, codomains, and images, composition, inverses, sequences, and countable sets.
- Expressions and Algorithms: expressions, parse trees, and algorithms.
