The branch of mathematics concerned with the manipulation of mathematical operations, variables, sets, groups, and fields. There are two main branches of algebra.
Elementary algebra is all about functions, combinatorics, and certain calculus concepts. The quadratic formula, the Binomial Theorem, and limits are all found here.
Abstract algebra has a lot to do with groups and set manipulation. Linear algebra, the study of vectors, can be found here as well.

The Abel-Ruffini Theorem states that there is no general formula to find the roots of a polynomial equation of degree 5 (quintic) or higher. This is an elementary algebra statement, but is proved using Galois Theory.

Get the Pre algebra mug.A sigma algebra (or σ-algebra) is to set algebras what sigma males are to males. The Borel hierarchy (the analog of the male hierarchy) is not a σ-algebra at any countable rank; instead the σ-algebra has the largest possible rank -- ω_1, the least uncountable ordinal (under suitable conditions e.g. the Polish space is uncountable. This is known as the non-collapse of the Borel hierarchy).
A σ-algebra is closed under countable union, countable intersection, and relative complement. This means σ-algebras arise naturally in the study of measure theory, where the measurable sets form a σ-algebra.

The algebra of Lebesgue-measurable subsets of R (i.e. the sets of real numbers with a well-defined "length", which is possibly infinity) form a sigma algebra.
