Napier's Bones

Napier’s Bones, invented by John Napier in 1617, were an early calculating tool designed to simplify complex arithmetic. These rods, made of wood, metal, or ivory, featured multiplication tables that allowed users to quickly multiply, divide, and even find square roots.

Each rod represented a digit, and by arranging them, users could perform calculations more efficiently - a significant innovation before the invention of mechanical calculators. Napier’s Bones became widely popular, revolutionising mathematical computations in trade, navigation, and science.
