Subtraction from a two-digit number
A group arrives at an airport to check in their 21 bags. They each want to keep a piece of hand luggage. Unable to work out how many bags they will need to check in, they call out for El Nombre who materialises and explains how to solve the problem. There are 6 in the group and each of them wants to take a bag as hand luggage, so they need to count back 6 from 21. They count back in ones and all agree that the answer is 15.
