This app was developed by students of computer science lessons at the Otto Hahn Gymnasium Tuttlingen with the help of the MIT AppInventors.
Since the GTR was replaced by a WTR at the grammar schools in Baden-Württemberg, linear systems of equations can no longer be solved with the calculator. This was the reason for the development of an app, which should help students, for example, to check the homework.
Rights and privacy:
Unlike many apps with similar functionality, this app is completely ad-free and does not include any InApp purchases. Furthermore, the app requires virtually no rights. In fact, the installer requests the right to view Wi-Fi status and Internet access (this is due to the AppInventor). In later versions, these rights should no longer be requested. These rights are not necessary for the functionality of the app and can be disabled on the smartphones. No personal data will be stored, evaluated or passed on.
functionality:
The OHG Tut Calculator has so far the following functions:
- Solving linear equation systems (LGS) of the type 2x3 and 3x4.
- Various calculations in the field of analytic geometry (distance between two points in space, center of two points in space, connecting vector of two points, length of a vector, cross product of two vectors, scale product of two vectors, angle between two vectors
- Solving a quadratic equation using the "midnight formula", also called abc formula
Further functions are to follow.

Unfortunately Android versions below 4.0 (Ice Cream Sandwich) and thus especially Android 2.3 (Gingerbread) can no longer be distributed via the Google Play Store. Upon request, a corresponding APK can be sent by email.
