### Course description

Learn algebra by investigating real-world problems involving variables, percentages, and rates. You'll focus on the key mathematical ideas and how to apply them to practical situations, not on tedious calculations. By the end of the course, you'll be putting algebra to work to evaluate discounts, manage constraints, and control costs.

### Topics covered

- Algebraic Expressions
- Equations
- Percent Change
- Proportions
- Rates
- Unit Rate
- Variables
- Writing Equations

### Prerequisites and next steps

This is a great course to use for starting or re-starting your study of math. Before you get started, you should be comfortable with numerical arithmetic (addition, subtraction, multiplication, and division), but no prior experience with algebra is needed.
