Math Class (Solve word problems involving subtracting minutes using the number line.)

The video tutorial explains how to determine the start time of a math class that ends at 11:15 and lasts 50 minutes. It guides viewers through the process of subtracting time using a number line, starting from 11:15 and moving backwards in increments of 10 minutes until reaching the start time of 10:25. The lesson emphasizes understanding time subtraction and using visual aids like number lines to solve word problems.
