ABSTRACT:
A hand-held calculator is provided, having a keyboard, visual display, microprocessor, and power source. The microprocessor is provided with a program that enables the user to enter a sequence of letter grades through the keyboard and compute a running average of the sequence. The current result of the average is visually displayed. The program also allows the user to delete entries from the sequence and adjust the average correspondingly, so that errors in the sequence may be corrected. Further, the program enables the user to calculate running averages of subsequences of grades simultaneously with the overall sequence average, so that grade averages for individual students may be computed at the same time that the grand average over all students is being computed. The display may be switched to indicate either the sequence average or subsequence average at the user's command. A mode switch is further provided to allow the user to switch the device to either the normal calculator function or the grade averaging function.
