Mathematics deals with the study of the measurement, properties, and relationships
of quantities, using numbers and symbols.
Mathematics is used throughout the world as an essential
tool in many fields, including natural science, engineering, medicine, and the
social sciences. Applied mathematics, the branch of mathematics concerned with
application of mathematical knowledge to other fields, inspires and makes use
of new mathematical discoveries, which has led to the development of entirely
new mathematical disciplines, such as statistics and game theory.
Mathematicians also engage in pure mathematics, or mathematics for its own sake,
without having any application in mind. There is no clear line separating pure
and applied mathematics, and practical applications for what began as pure
mathematics are often discovered
