### Motive for the creation ###

I''ve learned that some children understand how column addition works, but they think they don't because they stumble over their writing.'

It takes them (those children) 30 minutes to write the numbers, so when someone looks at their answer sheet, it looks like they don't understand arithmetic.


That's why we decided to create an app that allows them to do calculations by dragging number cards.

(Answers will not be judged, but instead a note to keep the process of the calculation.)

I would be very happy if more children could learn to do arithmetic and become more confident.
