This can be a fun distraction, as it is not easy to quickly recognize basic mathematical equations. The program is free so it does not take a monetary commitment. At the same time there is almost no content here besides very basic math. It does not get harder, nor does it have any more diverse options for game play. The interface is simple and basic, to a fault, and it can get rather boring before you even finish your first twenty question run. Its most positive attribute is that is saves your time and scores, compelling you to try and better yourself. This may be small reason to keep playing, but the eventual boredom is enough to counter that.
