24 sie 2021 · We begin this exercise set by exploring how to add two whole numbers together. To add 3 + 4, we find a set with three elements and a different set with four elements (having no elements in common with the first set). We combine the two sets and then count how many elements are in the union. This method is illustrated in the following exercise.
