What is Algebra?
Algebra is a branch of mathematics that uses symbols and letters to represent numbers and quantities in formulas and equations.
Key Concepts
- Variables: Letters that represent unknown values (x, y, z)
- Constants: Fixed values (2, 5, -3)
- Expressions: Combinations of variables and constants (2x + 3)
- Equations: Statements that two expressions are equal (2x + 3 = 7)
Basic Rules
- What you do to one side of an equation, you must do to the other
- Combine like terms to simplify
- Use inverse operations to isolate variables
