Study Notes
Algebra Overview
- Algebra is the study of mathematical statements using variables for unspecified values.
- It aims to determine for which values the statements are true.
- Linear algebra is a closely related field that investigates variables in systems of linear equations.
Algebraic Structures
- Abstract algebra studies algebraic structures, which consist of a set of mathematical objects with one or several binary operations defined on that set.
- It is a generalization of elementary and linear algebra, allowing for mathematical objects other than numbers and non-arithmetic operations.
- Algebraic structures are distinguished based on the number of operations they use and the laws they follow.
History of Algebra
- Algebraic methods were first used in ancient times to solve specific problems in fields like geometry.
- Subsequent mathematicians developed general techniques to solve equations independent of their specific applications.
- A rigorous mathematical formalism was developed in the 16th and 17th centuries.
- The scope of algebra broadened beyond a theory of equations to cover diverse types of algebraic operations and algebraic structures in the mid-19th century.
Variables and Constants
- A variable is a symbol that represents an unknown value or quantity that can change.
- Variables are often denoted by letters such as x, y, z, etc.
- A constant is a value that does not change.
- Examples of variables include the number of matchsticks required to repeat a given shape, and the length of a square.
- Examples of constants include the number of angles in a triangle.
Importance of Algebra
- Algebra allows us to express relations in any practical situation.
- Variables enable us to write general rules and formulas that can be applied to various problems.
- Algebra is relevant to many branches of mathematics, such as geometry, topology, number theory, and calculus, as well as other fields of inquiry, like logic and the empirical sciences.
