The computer algorithm helps the teacher by:
1. It saves time for the teacher so that she can do other tasks.
By using the computer program to record and calculate test grades, the teacher can automate the process, saving time that would have been spent manually calculating each student's average. This time-saving aspect allows the teacher to focus on planning lessons and other important tasks.
In summary, the computer algorithm streamlines the grading process, reduces the time spent on administrative tasks, and enables the teacher to allocate more time to teaching and preparing for lessons effectively.
