**Applied mathematics** is a branch of

mathematics that concerns itself with the application of mathematical knowledge to other domains. Such applications include

numerical analysis, mathematics of engineering,

linear programming,

optimization and

operations research,

continuous modelling[?],

biomathematics and

bioinformatics,

information theory,

game theory,

probability and

statistics,

financial mathematics,

actuarial science,

cryptography and hence

combinatorics and even

finite geometry[?] to some extent,

graph theory as applied to network analysis, and a great deal what is called

computer science. The question of what is applied mathematics does not answer to logical classification so much as to the sociology of professionals who use math. The mathematical methods are usually applied to the specific problem field by means of a

mathematical model of the system.

Engineering math describes physical processes, and so is often indistinguishable from theoretical physics[?]. Important subdivisions include:
