Calculated Industries GradeMatic 4000 - Averaging and Weighting Keys

Average: Finds a student’s grade aver-
age, adds it to the overall class aver-
age and prepares the calculator for a
new grade set entry.
Class Average: Calculates the class
average. To clear a class average,
press [Set] [Avg] [Avg]. Turning off the
calculator also clears the class aver-
age, but pressing [On/C] does not.
Weight Key: Used to weigh the grade
entry. Use with [Set] to build the
semi-permanent weight table for
automatic grade weighting.
Add to Memory: Adds the displayed
value to memory. This value remains
constant until added to or subtracted
from, or cleared. Since student grades
are automatically stored in memory
while class averaging, do not manu-
ally enter grades into memory.
