Study Notes
Algebra
Definition
- Algebra is a branch of mathematics that deals with the study of variables and their relationships, often expressed through symbols, equations, and functions.
Key Concepts
- Variables: Letters or 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 (or independent variable) exactly one output (or dependent variable).
Operations
- Addition and Subtraction: Combining like terms to simplify algebraic expressions.
- Multiplication and Division: Following the order of operations (PEMDAS) to evaluate expressions.
- Exponents and Roots: Raising variables to powers and finding roots of expressions.
Solving Equations and Inequalities
- Linear Equations: Equations in which the highest power of the variable is 1.
- Quadratic Equations: Equations in which the highest power of the variable is 2.
- Inequalities: Statements that express a relationship between two expressions, using greater than, less than, or equal to symbols.
Measurement
