Quadratic equations are not included in the 1st build of Math Classroom Challenge (Windows) and Math Street Challenge (iOS-AR), but you can expect to find them soon in new builds.
Meanwhile, the Augmented Version (iOS) version of Math Street Challenge is now at the App Store, and the Windows version, Math Classroom Challenge and its Oculus version is in final test for being released next June 1st. Thank you for your support.
We are happy to inform that Math Clasroom Challenge is online now on Steam, in standard and Oculus Version. But be aware that both versions are the same, so you only need to activate or deactivate your Oculus Rift device to play with VR. If not active, the game will run as usual in a standard monitor.
You can read the manual and features here.
Math Classroom Challenge will be available in two weeks. Thank you for your interest.
