This math topic focuses on calculating elapsed time in a negative format, specifically identifying how many hours and minutes earlier one time is compared to another. Each problem involves comparing two clock times and determining the time difference in terms of hours and/or minutes. All the comparisons are made within the same hour, typically involving half-hour increments. The objective is to strengthen the ability to understand and compute time intervals, particularly in a straightforward context.
