HistoryC. 3000 BCMesopotamia and Egyptlow confidence

Ancient Egypt began using arithmetic, algebra, and geometry shortly after Sumer, Akkad, and Assyria, around 3000 BC.

Notes on verification

Well supported by Wikipedia and MacTutor sources placing both Mesopotamian and Egyptian mathematical traditions around 3000 BC, though the precise sequencing ('shortly after') is imprecise since some evidence suggests Egyptian numerical records may be contemporaneous or even slightly earlier.
