Step 1 :The number of different schedules is the product of the number of choices for each class. This is because for each choice of math class, there are 13 choices for English class, 5 choices for communications class, and 6 choices for elective.
Step 2 :So, the total number of different schedules is calculated as follows:
Step 3 :\(8 \text{ (math choices)} \times 13 \text{ (English choices)} \times 5 \text{ (communications choices)} \times 6 \text{ (elective choices)}\)
Step 4 :This simplifies to:
Step 5 :\(8 \times 13 \times 5 \times 6\)
Step 6 :Which equals:
Step 7 :\(\boxed{3120} \text{ different schedules}\)
