Isopsephy

Isopsephy (*iso* meaning “equal” and *psephos* meaning “pebble”) is the Greek word for the practice of adding up the number values of the letters in a word to form a single number. The early Greeks used pebbles arranged in patterns to learn arithmetic and geometry. A Greek synonym for the word “pebbles” is kalkuli and is the origin of the word “calculate.”
