Algebra, from the Arabic al-jebr, meaning “reunion of broken parts”, is one of the wide-ranging parts of mathematics, combined with number theory, geometry, and analysis. Algebra can basically be considered as doing computations much like that of arithmetic with non-numerical mathematical objects. Initially, these objects were variables that represented either numbers that weren’t yet...

Geometry

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science...

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation...
