Problem 4

At the start of the day, there were 30 students in the classroom. That number grew and shrank throughout the day. The integers \(4,-1,-2\), and 0 represent the change in the number of students in the classroom. List the integers in order from least to greatest. Explain the meaning of zero in this situation.

Expert verified

The integers in order from least to greatest are: -2, -1, 0, 4. In this situation, zero represents no change in the number of students in the classroom, meaning there were neither students leaving nor joining the classroom at that point in time.
