To Jane Moore: Thanks for the review (from the developer). Maybe you can describe the particular situations? From my point of view, it serves to prevent the use of normal calculators with decimals. Is a calculator for children who only know division and remainder positive integers (natural numbers). But do not know the division with decimals. And at the same time serves to help read the numbers and operations. In a more advanced state of training, can be re-used for operations with large numbers, that are beyond the capabilities of conventional calculators. Many thanks! Is the first time that I see a review of my works in the Merlot site from 2001. Maurici

This calculator will be very useful in particular situations. It will not be reviewed by the Teacher Education Board because its use is so specific.
