Historical Note

This presentation of the results of an operation in a table is attributed to the Greek mathematician and philosopher Pythagoras, to whom we also attribute many other results. The table allows us to quickly locate the properties of certain numbers or certain operations, like the multiples of 9 in a multiplication table, where we can quickly observe that the digital sum of the products is also a multiple of 9.
