Is set theory useful?

Set theory is used throughout mathematics. It is used as a foundation for many subfields of mathematics. In the areas pertaining to statistics, it is particularly used in probability. Much of the concepts in probability are derived from the consequences of set theory.

What grade do you learn set theory?

Basic ideas should be in fifth-sixth grade. They should be used when appropriate (often) in all algebra classes. More detailed (but naive) set theory should be covered around ten-twelfth grade. All students entering college should be familiar with it.

What are the prerequisites for set theory?

Reading Jech generally requires no prerequisites, but it is good to be familiar with the basics of logic and very naive set theory before reading it. The first part of the book, which is the introductory part, covers a lot of basic topics in modern set theory, and most of the proofs are relatively complete.

Is set theory math?

Set theory is the mathematical theory of well-determined collections, called sets, of objects that are called members, or elements, of the set. Pure set theory deals exclusively with sets, so the only sets under consideration are those whose members are also sets.
