The invention of multiplication tables is attributed to the Greek philosopher and mathematician Pythagoras of Samos (580-495 BC).
The evolution of multiplication tables reached one of its milestones when the mathematician Crele also created one of 3 digits (from 000 to 999).
Everything was relegated from 1642 onwards with the appearance of the first automatic calculating machine by the French mathematician and inventor Blaise Pascal.
