This is the graduation exercise for the basic use of spreadsheets. We combine rules and addressing to have students build their own hundreds table in the fewest steps. There are many ways of doing this and students can be as creative and exploratory as they want. Nor should they feel limited to tables that start at 1 and go to 100. These rules, these patterns should enable them to start anywhere and build any size table they can imagine. We strongly encourage students to stretch their minds here and to think outside of this box.
