# Mathematical logic facts for kids

**Mathematical logic** is a field of mathematics that tries to formalize logic so that it can be used for mathematics more easily. Logic is about reasoning, and mathematical logic shows this with symbols. Most of mathematical logic was developed in the 19th and 20th century.

This field can be said to have four main sub-fields:

- set theory
- the study of mathematical proofs
- the study of recursion, and
- model theory
