Abstract: A server apparatus includes a processor. The processor is configured to perform: calculation target data receiving processing, group ID receiving processing, data registering processing and integrated calculation result transmitting processing. The calculation target data receiving processing receives calculation target data which is to be output from an information display device. The group ID receiving processing receives a group ID. The data registering processing registers the calculation target data received in the calculation target data receiving processing in association with the group ID received in the group ID receiving processing. The integrated calculation result transmitting processing integrates each calculation target data registered in association with the group ID in the data registering processing for each group ID and transmits a calculating result based on the integrated data.
