Algebra Basics
If algebra has felt abstract, the right visuals make it click fast. This path starts with the idea of balance, then moves into solving linear equations and testing what happens when you change both sides of an equation. By the end, you'll have a practical sense of variables, expressions, and how algebra turns into graphable relationships.
Learning Path
Equation Balance Scale
See equations as two sides of a scale and learn why every operation must stay balanced.
Open →Linear Equation Solver
Practice solving one-step and multi-step equations while checking each move along the way.
Open →Equation Balance & Intro Algebra Lab
Try guided algebra tasks that connect variables, expressions, and equations in a hands-on setting.
Open →Algebra Basics Checklist
Keep these core ideas in mind as you study:
- Variables stand for unknown or changing values.
- Expressions show operations; equations show two equal quantities.
- Use inverse operations to isolate the variable, then check your answer by substitution.

Common Questions
What is the difference between an expression and an equation?
An expression is a math phrase with numbers, variables, and operations, while an equation says two expressions are equal.
Why do I need to do the same thing to both sides of an equation?
Because an equation is like a balanced scale: changing only one side would break the equality.
