Algebra is the branch of mathematics that studies certain abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication.
A typical sequence of secondary-school (grades 6 to 12) courses in mathematics reads: Pre-Algebra (7th or 8th grade), Algebra I, Geometry, Algebra II, Pre-calculus, and Calculus or Statistics. However, some students enroll in integrated programs [3] while many complete high school without passing Calculus or Statistics.
Last month, Zynga added two paid features to Words With Friends that -- well, there's no getting around it -- were borderline cheat tools. For the cost of 10 Tokens or roughly $1.50 USD, Tile Pile ...

High scoring tiles: The high scoring tiles (e.g. Q, Z, V, K) earn the most points, even with short words! Other players: Remember the words other players seem to find a lot. Look for those words, too.
In mathematics, a basic algebraic operation is any one of the common operations of elementary algebra, which include addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power). [1] These operations may be performed on numbers, in which case they are often called arithmetic operations.
Let V be a finite-dimensional vector space over k....Let (e i) 1≤ i ≤ n be a basis for V....There is an isomorphism of the polynomial algebra k[T ij] 1≤ i, j ≤ n onto the algebra Sym k (V ⊗ V *)....It extends to an isomorphism of k[GL n] to the localized algebra Sym k (V ⊗ V *) D, where D = det(e i ⊗ e j *)....We write k[GL(V ...
