Rule-Of-Three Calculator is a simple and practical application that will help you in solving the rule-of-three, which is a math problem that has a missing value. The App provides you with an interface that allows you to enter three known values and hit the "Calculate" button.

You can enter the values by using the "Edit" option or by using the "Edit and Insert" option.

This is the first version of the app, and we are planning to release the second version soon.
