This math topic focuses on practicing calculations related to negative elapsed time. Students are required to solve problems that involve subtracting time (a combination of hours and minutes) from a given starting time. The objective is to calculate and determine what the new time would be after the subtraction. Each problem is structured around subtracting time increments, often crossing over hourly boundaries, challenging the student's understanding of time concepts and their ability to manipulate hours and minutes effectively.
