Basic Algebra

Basic Algebra topics are the very beginning of learning Algebra. When you start on these topics, you're expected to have little more than Arithmetic knowledge (you know, those problems to do with "+", "-", "÷", and "×"). You'll also need to be familiar with Pre Algebra topics, but you don't need to worry about that now. You can easily refer back to the Pre Algebra topics later if you need to.

This section is designed specifically for those who are beginning Algebra, but will be useful for reference if you're learning Intermediate or Advanced algebra topics. You'll find a list of topics followed by a brief description.

How do you use these pages? If you're starting out, I recommend that you start with Algebraic Expressions, Algebraic Equations, Algebraic Factoring and Exponents. These will give you the foundation needed to understand the other basic algebra topics.

If you just want to find information to solve a problem, go to the topic that is most obviously relevant to your problem, and read. What if you can't solve a problem with the knowledge from one topic? Recognize that some problems might need a combination of different techniques from Pre Algebra and basic Algebra. Identify the techniques and you'll solve the problem easily.
