# Algebra 1. Basic Notions of Algebra by A. I. Kostrikin, I. R. Shafarevich

By A. I. Kostrikin, I. R. Shafarevich

This e-book is wholeheartedly prompt to each pupil or consumer of arithmetic. even supposing the writer modestly describes his e-book as 'merely an try to discuss' algebra, he succeeds in writing a very unique and hugely informative essay on algebra and its position in sleek arithmetic and technology. From the fields, commutative earrings and teams studied in each collage math direction, via Lie teams and algebras to cohomology and classification idea, the writer indicates how the origins of every algebraic thought will be concerning makes an attempt to version phenomena in physics or in different branches of arithmetic. similar common with Hermann Weyl's evergreen essay **The Classical Groups**, Shafarevich's new ebook is bound to develop into required interpreting for mathematicians, from newcomers to specialists.

The answer will not change when we change the association (or grouping) of the numbers. Associative Property of Addition In symbols: a ϩ (b ϩ c) ϭ (a ϩ b) ϩ c In words: Changing the grouping of the numbers in a sum will not change the result. Associative Property of Multiplication In symbols: a(bc) ϭ (ab)c In words: Changing the grouping of the numbers in a product will not change the result. The following examples illustrate how the associative properties can be used to simplify expressions that involve both numbers and variables.
