From around 3000 BC, the Mesopotamian states of Sumer, Akkad, and Assyria began using arithmetic, algebra, and geometry for taxation, commerce, trade, and astronomy.
Notes on verification
Core claim (arithmetic/geometry used for taxation, trade, astronomy from ~3000 BC) is well corroborated by independent academic sources. The inclusion of 'algebra' at this early date is an imprecise generalization, as true algebraic methods are typically dated to the Old Babylonian period (c. 2000-1600 BC), not c. 3000 BC.
