## What is Teamwork addition?

Practice making calculations with the numbers assigned to you. Play alone or with a friend. Then you play on the same team and collect points together.

Each game takes 60 seconds. If you do well, you will gradually get more difficult numbers.

Sometimes it is not possible to make a calculation with the numbers you have. Then you can press the +1 button, and one of the numbers becomes one more. If you press four times, all the numbers will be replaced.

The app does not contain advertisements, links or purchases.
