A differential equation is a mathematical equation that relates some function with its derivatives.

In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two.

Because such relations are extremely common, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology.

Calculus (from Latin calculus, literally "small pebble used for counting") is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.

It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus.

Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.

Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Gottfried Leibniz.

Today, calculus has widespread uses in science, engineering and economics.

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.

Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers), structure, space, and change.

There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.

An electronic calculator is a small, portable electronic device used to perform operations ranging from basic arithmetic to complex mathematics.
