"Add" - play random sums or create your own challenging sums

"Add" is a app built for the whole family and for all ages. Keep your manual calculation skills up to date and help your children learn how to calculate sums via 3 different game modes.

"Add" allows you to play either in "Game mode" and be challenged by increasingly more difficult sums (you decide your preferred difficulty!), or, via its simple "Calculator" function, you enter the sum that you wish to be challenged upon, and then, you use the "Game" screen to find the sum's result by entering all the digits making the sum's result and, optionally, the carry forwards digits for each column of the sum.

Multi Language support:
- "Add" supports English, French, Spanish, German, Italian and Portuguese
