Packaging Books

The video tutorial explains how Amy, who works at a bookshop, can pack 320 books into packages of 10 using repeated subtraction. Initially, subtracting 10 repeatedly is shown to be cumbersome, requiring 32 subtractions. The tutorial then demonstrates a more efficient method by subtracting larger multiples of 10, such as 100, to reduce the number of steps. This approach results in 32 packages with no remainder. The lesson concludes by highlighting the concept of finding quotients and remainders through repeated subtraction of multiples of 10.
