The determinant of a square matrix is a number associated with the matrix, which is fundamental for the study of a square matrix; for example, a square matrix is invertible if and only if it has a nonzero determinant and the eigenvalues of a square matrix are the roots of a polynomial determinant.
From 2012 figures, 79% with A*, 48% of A, 15% of B and 1% of grade C chose Maths in the 6th form. For English, History and Geography, 30% with grade B, and 10% with grade C chose the course in the 6th form. The House of Lords July 2012 report Higher Education in STEM Subjects recommended that everyone study some type of Maths after 16. For less ...
Mathematics education in the United States varies considerably from one state to the next, and even within a single state. However, with the adoption of the Common Core Standards in most states and the District of Columbia beginning in 2010, mathematics content across the country has moved into closer agreement for each grade level.
Mathematics majors study additional other areas within pure mathematics—and often in applied mathematics—with the requirement of specified advanced courses in analysis and modern algebra. Other topics in pure mathematics include differential geometry , set theory , and topology .
The parallelogram defined by the rows of the above matrix is the one with vertices at (0, 0), (a, b), (a + c, b + d), and (c, d), as shown in the accompanying diagram. The absolute value of ad − bc is the area of the parallelogram, and thus represents the scale factor by which areas are transformed by A.

Grading in education is the application of standardized measurements to evaluate different levels of student achievement in a course. Grades can be expressed as letters (usually A to F), as a range (for example, 1 to 6), percentages, or as numbers out of a possible total (often out of 100).
In francophone schools or CBE Schools from kindergarten to Grade 9, an alternative grading system is used instead of percentages and letter grades: numbers 1 through 4 are used (4 is excellent, 3 is good, 2 is average, and 1 is below average. Note: not all schools utilize a +/− system when giving grades. Some just give the generic grade.
