Alb Subtractions

• App developed to help my sons to learn and practice subtractions for school / institute, on an easy way for them: Not studying, but playing: It works! (...And not only for children, but for all ages!).


• Learn, play and practice subtractions.

• Designed for students of any grade / age: Primary, secondary, ESO... Or for anyone that wants to learn or practice subtractions.

• 2 app versions:

- Free / Demo: FREE, with NO ads, version limited to subtractions of 3 digits. I would suggest to start with this free version. Then, once you or your son is confident with them, go to the complete version, in which you can configure the number of digits, and the number of decimals.

- Complete version: Complete version with NO ads. Cheap! (Cost less than inviting to a coffee). ;-)


• Number of digits and number of decimals can be configured on the complete version.

• Resizable screen: Fits in any screen size, and can be adjusted for the smallest phones, to the biggest tablets, either in vertical, either in horizontal mode.

• Multilanguage: Set the menus in English, Spanish or French.

• App does not require any permission on Android 6 (for some previous android versions, Android sets WIFI permissions to the app, although not used, neither needed).

• In case of any problem, or if you think adding any additional feature would be helpful, please, send an email to AlbComentarios@gmail.com

• Play with your children to check who scores more, or simply, let the children play 10 minutes a day... In few days, they will be very confident on subtractions without studying.

• With this app, you can:
- Practice and learn to do subtractions.
- Change the study of subtractions into a game to learn them.

• This app is simply a game that replaces the typical "pass the lesson" with Q&A (questions and answers): The app asks a different subtraction every time and check your responses. Based on play and practice, you will learn to do subtractions quickly, as you are asked at school / college (primary / secondary).

• You can configure the subtractions as you are asked in your school or institute (primary, secondary / ESO).

• App Name:
Alb Subtractions - Alb Restas - Alb Soustractions
