The author of Valgetal and Matego

Hello! My name is Rinze. I've studied applied physics and I've been working as a teacher for a while. At that time I ''fell in love'' with educational programs. I think it's quite refreshing to play sometimes with a nice program. My ideal software is of course instructive, with a clear interface, but it must also be a challenge. That's the reason I always try to make them like a game with a possibility to get a high score.
