Study Notes
Algebra
Definition
- Algebra is a branch of mathematics that deals with the study of variables and their relationships, often expressed through the use of symbols, equations, and functions.
Key Concepts
- Variables: Symbols that represent unknown values or quantities.
- Constants: Numbers that do not change value.
- Algebraic Expressions: Combinations of variables, constants, and mathematical operations.
- Equations: Statements that express the equality of two algebraic expressions.
- Functions: Relations between variables that assign to each input (domain) exactly one output (range).
Types of Algebra
- Elementary Algebra: Focuses on solving linear equations and inequalities, quadratic equations, and graphing linear equations.
- Intermediate Algebra: Covers systems of linear equations, quadratic equations, and functions.
- Advanced Algebra: Includes group theory, ring theory, and Galois theory.
Algebraic Operations
- Addition: Combining like terms in an algebraic expression.
- Subtraction: Combining like terms with opposite signs.
- Multiplication: Combining algebraic expressions using the distributive property.
- Division: Reversing the multiplication operation.
Solving Equations
- Linear Equations: Ax + By = C, where A, B, and C are constants.
- Quadratic Equations: Ax^2 + Bx + C = 0, where A, B, and C are constants.
- Systems of Equations: Sets of linear equations with multiple variables.
Graphing
- Cartesian Coordinate System: A system with x and y axes that intersect at the origin (0, 0).
- Graph of a Function: A visual representation of a function's output values.
Real-World Applications
- Science and Engineering: Algebra is used to model real-world phenomena, such as population growth and electrical circuits.
- Computer Science: Algebraic concepts are used in computer programming and coding.
- Data Analysis: Algebra is used in data analysis and statistical modeling.
