This math topic focuses on calculating the negative elapsed time between two clocks in hours and minutes. Each problem presents two different times displayed on clocks and requires determining how many hours and minutes earlier one time is compared to the other. It's a more advanced exercise in time calculation, challenging students to think about time in a non-standard, backward-counting manner. This topic is part of a broader unit on advanced negative elapsed time.
