For a given combination of values for the free variables, an expression may be evaluated, although for some combinations of values of the free variables, the value of the expression may be undefined. Thus an expression represents an operation over constants and free variables and whose output is the resulting value of the expression. [22]
When q ≠ 2, the group is simple, and when q = 2, it has a simple subgroup of index 2 isomorphic to 2 A 2 (3 2), and is the automorphism group of a maximal order of the octonions. The Janko group J 1 was first constructed as a subgroup of G 2 (11). Ree (1960) introduced twisted Ree groups 2 G 2 (q) of order q 3 (q 3 + 1)(q − 1) for q = 3 2n ...
This list of mathematical series contains formulae for finite and infinite sums. It can be used in conjunction with other tools for evaluating sums. Here, is taken to have the value
Mathematics is the study of representing and reasoning about abstract objects (such as numbers, points, spaces, sets, structures, and games).Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, and the social sciences.
The number of known mathematicians grew when Pythagoras of Samos (c. 582 – c. 507 BC) established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". [2] It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins.

An m × n matrix: the m rows are horizontal and the n columns are vertical. Each element of a matrix is often denoted by a variable with two subscripts.For example, a 2,1 represents the element at the second row and first column of the matrix.
