Review from Principal Adam Gorny:
Thank you for your program.
We had a chance to work with your program for a while and find it rather interesting. For sure, it reinforces definitions of numbers - meaning of prime numbers, composite numbers, counting numbers etc. It also interestingly manipulates them to form relationships, which again bring to life the definitions. What we like the most, both tutors and students, is a help file with glossary of terms, some terms are not wildly known, I wish Microsoft would follow your example.
I must admit that some puzzles were even to hard on the "experts" (read TUTORS), but then that makes them grow as well.
Over all you get "EXCELLENT" mark.
