Romanis

Czy znasz zasadę pisania liczb arabskich od rzymskich i viceversa?

This app is a good practice to learn roman numerals. Questions are randomly created, so you can have endless series of exercises. It is also useful both for teachers and for students.

If the answer is right, long press "Correct" to go on; if it is wrong press Enter to retry.

Furthermore, it could be used with "Numeri romani", app by the same author.
