On July 1, 2023, the productive operation of our new service “STACK-Maxima” has started. The service gives operators of e-learning systems such as Ilias or Moodle the possibility to interpret mathematical questions resp. exercises created via STACK algebraically, thus the service provides a CAS calculator as a backend. The service was already described in the last GWDG News 6/2023. If you are interested or have any questions, please contact us at stack-support@gwdg.de.
