How To Use MathOtter
This web application is easy to use. It runs in the browser on any device (phone, laptop, tablet, etc.) that has internet connectivity. You don't need to download or install anything. You can bookmark the web address for easy access.
An unlimited number of free practice problems (and answers) are arranged into main categories. Each category has a menu of individual topics. (Except the Random Quiz category, which has a mix of problems from all topics.)
When you complete a practice problem, you can check the answer. If you need help, the "i" icon shows how to solve the problem type -- always free.
The "Show Me How" button provides a step-by-step solution for some problems. For others an optional explanation to the problem, generated by an AI system is available. (10 free AI requests are included if you create a free account. You can purchase more, if needed.)
Here are some screenshots that illustrate how to navigate the app:
