We created this app because we believe learning and mastering the long addition method for solving addition problems is crucial in order to gain a solid understanding of addition.

This app has two features. First, it includes a Long Addition Calculator that shows you step by step how to add any two numbers using the long addition method. Second, it includes a Long Addition Test, where you can put your skills to the test by solving practice addition problems.

We recommend that you start by using the Long Addition Calculator. Simply enter different addition problems to see how we solve them using the long addition method. Then try the Long Addition Test to test your new long addition skills.

The app is fast, intuitive, and easy to use. It is a standalone app, which means that it will work perfectly fine in places with little or no Internet access.

We hope that the Long Addition app will become one of your favorite math apps.
