element - correct answer ✔is a collection of anything - numbers, letters, words, or objects



finite set - correct answer ✔Finite means we can count the number of elements.

Equivalent sets - correct answer ✔are those that have the same cardinality, or number of elements



Cartesian product - correct answer ✔is the product of two sets A and B such that every element of set
A relates to every other element of set B to form ordered pairs.
