Notes:

Mathematics has several broad areas, including pure mathematics, applied mathematics, computational mathematics and mathematical statistics.
Pure mathematics focuses primarily on abstract structures, mathematical relationships and proofs.
Applied mathematics uses mathematical methods to solve problems in science, engineering, economics and other fields.
Some branches overlap. For example, real analysis and complex analysis are subfields of mathematical analysis, while graph theory is a major part of discrete mathematics.
There is no single universally accepted list of all branches of mathematics; new specialized fields and interdisciplinary areas continue to develop.
