Professor Plusminus

Help Professor Plusminus to solve the calculations and launch his rocket!

Professor Plusminus allows students from elementary scool to train basic calculations. You can configure every basic calculation separateley (which numbers to take, in which range the result will be and so on). You can also configure which types of calculations will be trained. Within the defined borders the software will provide random calucations which must solved by the students. The number of calculations for each round is configurable as well.
After the calculations are solved, the software provides feedback which calculations were solved correctly and which where wrong. The wrong ones must be redone, until every calculation was entered correctly. For training it can be configured that the wrong calculations will be requested in the following rounds as well.

The program allows you to store several configurations, so you can use the software for several children. For motivation an animation will be shown. For later analysis the software provides a statistic view, where the number of errors as well as the needed time is shown in a graph.
