Applied mathematics is a branch of mathematics that concerns itself with the mathematical techniques typically used in the application of mathematical knowledge to other domains.Today, the term applied mathematics is used in a much broader sense. It includes the classical areas of ****ysis such as differential equations, as well as linear algebra, numerical ****ysis, probability, operations research, and other areas. Recently, fields such as number theory and topology, often thought to be pure mathematics, have become increasingly important as applications, though they are not generally considered to be part of the field of applied mathematics per se.
