Trigonometry (from Greek , "triangle" and , "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles.

The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Algebra (from Arabic "al-jabr" meaning "reunion of broken parts") is one of the broad parts of mathematics, together with number theory, geometry and analysis.

In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

As such, it includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra.

Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics.

Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than .

In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values.

Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis.

Discrete objects can often be enumerated by integers.

More formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets (sets that have the same cardinality as subsets of the natural numbers, including rational numbers but not real numbers).

However, there is no exact definition of the term "discrete mathematics." Indeed, discrete mathematics is described less by what is included than by what is excluded: continuously varying quantities and related notions.

Geometry (from the; "earth", "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.

A mathematician who works in the field of geometry is called a geometer.

In mathematics education, precalculus is a course with university or high school level algebra and trigonometry that is designed to prepare students for the study of calculus.

Schools often distinguish between algebra and trigonometry as two separate parts of the coursework.
