Mathematics is the subject which is needed in almost every walk of life like to purchase and sell, to figure costs, to calculate real interest rates on loans, to fill out income-tax forms, to prepare recipes and in many other ways. Mathematics comprise of algebra, arithmetic and geometry. The new era has witnessed the use of these fields not only in physical sciences or biological and medical sciences but also increasingly in the social sciences. Mathematics is the only subject which is important to study any other subject that is science, physical, biological and social. Use of statistical methods, linear programming and other mathematical technology is increasing with every passing day in subjects like economics, business administration, psychology, etc.

Mathematics is a study of form, structure, operations and relationships. Through the use of numbers and symbols mathematics involves study of quantities and relations.

Arithmetic deals with quantities expressed in numbers and Algebra uses quantities and relationships expressed in symbols.

Geometry includes quantities associated with figures in space while trigonometry deals with relationships of angels. Analytical geometry applies algebra to geometric studies.

Calculas deals with pairs of associated quantities.

Theoretical mathematicians study mathematical forms and the underlying principles in order to apply them to solve mathematical problems.

Applied mathematicians develop actual techniques and approaches to solve problem in physical, biological as well as social sciences.

Consultant mathematicians direct industrial research techniques which is the main area concerned in teaching.

Statistics being the main field of mathematics which enables us to interpret and collect information from any field is applied to most work fields and helps professionals to apply appropriate methods for interpreting data. Fields like agriculture, business, education, sports environment, medicine, economics, law, planning uses statistical data.
