Subtracting None and Subtracting All

Sam and Stella plan to study together, with Sam bringing plums for both. Sam gives more plums to Stella, demonstrating generosity. The video uses this scenario to teach subtraction, showing that subtracting zero from a number leaves it unchanged, while subtracting a number from itself results in zero.
