A times-table square with most of it rubbed out. The numbers along the top and down the side — the headers — are hidden, and so are most of the products inside.
Every product sits where a row meets a column, so if you know the product and one of the headers, a division gives you the other header. Each new header unlocks more squares, and once you know a row and a column header, their meeting square is just a multiplication.
