Get a pen or pencil, some paper and a calculator. You can practice an unlimited number of GED math problems provided by MathOtter.

The MathOtter web app is an internet accessible tool that runs in a browser. You can use it on your phone, laptop or tablet and practice anytime, anywhere you have internet connectivity. You must have internet connectivity to run the app.

For the best experience on your phone, add MathOtter to your home screen. (Scroll down to see instructions.)

You can get started by using the "Search" feature on the home screen to find specific problem types or topics. Or, choose a category from the home screen:

• Math Skills
• Algebra
• Geometry
• Word problems
• Data analysis
• Random Review

Each category (other than the Random Review) has a list of problem types you can work on.

You can work on a specific problem, then tap or click "Show Answer" to see if you got it right.

If you got the correct answer, great! If not, you can tap or click the round "i" icon to get more information about the problem concept with some example problems and solutions, or tap or click the "Show Me How" button to get a step-by-step explanation of how to do the problem.

Practice as little or as much as you want -- there's no tracking going on. But, remember: Practice Makes Perfect!
