Mathematics is based on fundamental rules. From basic math to differential and integral calculus, it is the adhesion to the rules that make math the language of science and innovation.  Algebra facilitates the declaration of what is known about a variable or variable using something akin to a mathematical sentence as an Equation of an Inequality.  Geometry deals with space and the properties of figures, such as size and shape. Trigonometry is the study of triangles and angles and their relationship,  the greatest example of which is seen in the great Pyramids of Egypt. Calculus deals with variable, or changing quantities providing a means to measure change. Mathematics is the underpinning of modern civilization

The WikiPedia site can be used just as you would an encyclopia to learn about mathematics. We have placed it first in the list because of its broad range of mathematical information.

Making Mathematics Count
According to a government-backed report published this week, maths education is failing on every account and needs a fundamental multi-million pound overhaul. The current system of GCSEs and A-levels is not meeting the needs of students, teachers, employers or universities, the report's author, Professor Adrian Smith, said today as he published the damning 186-page document, the result of a 15-month inquiry into the future of maths in schools. Less than 10% of GCSE students go on to take A-level maths, and less than 10% of A-level students go on to a maths degree, the report says. Incentives should be considered to halt the "disastrous" decline in pupils taking maths at A-level - examples mooted include waiving university tuition fees for maths students.
