====Algebra====
[[Algebra]] includes the study of algebraic structures, which are sets and operations defined on these sets satisfying certain axioms. The field of algebra is further divided according to which structure is studied; for instance, group theory concerns an algebraic structure called ''group''.

[[Calculus]] studies the computation of limits, derivatives, and integrals of functions of real numbers, and in particular studies instantaneous rates of change. [[Mathematical analysis|Analysis]] evolved from calculus.

====Geometry and topology====

[[Geometry]] is initially the study of spatial figures like circles and cubes, though it has been generalized considerably. [[Topology]] developed from geometry; it looks at those properties that do not change even when the figures are deformed by stretching and bending, like dimension.

====Combinatorics====
[[Combinatorics]] concerns the study of [[Countable set|discrete]] (and usually [[Finite set|finite]]) objects. Aspects include "counting" the objects satisfying certain criteria (''[[enumerative combinatorics]]''), deciding when the criteria can be met, and constructing and analyzing objects meeting the criteria (as in ''[[combinatorial design]]s and [[matroid]] theory''), finding "largest", "smallest", or "optimal" objects (''[[extremal combinatorics]]'' and ''[[combinatorial optimization]]''), and finding [[algebra]]ic structures these objects may have (''[[algebraic combinatorics]]'').

====Logic====

[[Logic]] is the foundation that underlies [[mathematical logic]] and the rest of mathematics. It tries to formalize valid reasoning. In particular, it attempts to define what constitutes a proof.

====Number theory====
The branch of mathematics deals with the properties and relationships of numbers, especially positive integers.
[[Number theory]] is a branch of pure mathematics devoted primarily to the study of the integers and integer-valued functions. German mathematician Carl Friedrich Gauss said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."
Number theory also studies the natural, or whole, numbers. One of the central concepts in number theory is that of the [[prime number]], and there are many questions about primes that appear simple but whose resolution continues to elude mathematicians.
