Algebra is a branch of math dealing with symbols and rules.

It uses variables (like x and y) to represent unknown values.

Expressions are combinations of numbers, variables, and operations.

Equations show two expressions are equal (e.g., x + 2 = 5).

Solving equations means finding the value of the variable.

Like terms can be combined (e.g., 2x + 3x = 5x).

The distributive property is a key rule: a(b + c) = ab + ac.

Inequalities compare expressions using >, <, ≥, or ≤.

Algebra is used in science, engineering, and daily problem-solving.

Learning algebra builds logical thinking and analytical skills.
