Original Note:
Due to the small diameter of the roller the equations repeat after every 10 lines, which also suggests that you can only have 10 different combination, resulting in 100 total equations. It can still have a sufficient learning effect for children in first and second grade. https://www.understood.org/en/articles/when-kids-learn-addition-subtraction
