This math topic focuses on calculating elapsed time using subtraction and involves changing the time by subtracting minutes from a given initial time. Each problem provides a starting time and asks students to determine the new time after subtracting a specified number of minutes, which varies among the questions. This set of problems is from a broader unit on negative elapsed time, designed to introduce students to time calculations across different hours and potentially into negative durations or previous hours. The problems cater to preparing students for accurate clock reading and time manipulation skills.
