Inside a mysterious jar there is some water. Turn the page and the water becomes the sea. In that sea, there is an island and on that island there are two countries, and so on until the reader has counted to over three million. Mitsumasa Anno’s books use detailed watercolors to show mathematical concepts. Text and pictures combined give a memorable lesson on factorials.
