This math topic focuses on solving problems related to elapsed time, specifically incorporating scenarios where there is a need to calculate time after a negative change. It aims to enhance the ability to read clocks and adjust times backward, either in hours or minutes, to determine resulting times. Each question presents a different scenario where learners must compute and identify the correct time after deducting specified full hours or minutes from a given starting time.
