Algebra is a branch of Mathematics that uses symbols (like x, y) to represent unknown values and relationships.
Here are the key specifics:
Variables & Constants: Letters (x, y) represent unknowns; numbers are fixed values.
Expressions: Combinations like 3x + 5 (no equals sign).
Equations: Statements like 2x + 3 = 7 that can be solved.
Operations: Addition, subtraction, multiplication, division applied to variables.
Functions: Rules that relate inputs to outputs (e.g., f(x) = x).
Polynomials: Expressions with multiple terms (e.g., x + 2x + 1).
Factoring & Expansion: Breaking or building expressions.
Graphs: Visual representation of equations on coordinate planes.
Inequalities: Expressions showing greater/less than (>, <).
