Etymology
The word 'arithmetic' traces its lineage directly to ancient Greek. It originates from arithmētikē (tekhnē), meaning "the (art) of counting," which itself is derived from arithmos, "number." This Greek term passed into Latin as arithmetica and subsequently into Old French before entering Middle English. The core logic is beautifully preserved: the modern abstract discipline of arithmetic remains fundamentally "that which is related to numbers," directly reflecting the literal meaning of its constituent Greek morphemes.
