mathematics [plural n., usually treated as singular]
the branch of science concerned with number, quantity, and space, either as abstract ideas [pure mathematics]
or as applied to physics, engineering, and other subjects [applied mathematics].
- ORIGIN from Greek mathema ‘science’, from manthanein ‘learn’.
Mathematics is one of the core learning areas, with language, in all schools. While it can be studied as an individual subject, it is also found in most others through the use of its numbering and measurement systems. It is especially important in Science subjects.
This page looks at core areas of Mathematics - Algebra, Calculus, Fractions, Geometry, Problem Solving, Real Life Mathematics and other special areas.
