One famous tablet, known as Plimpton 322, lists number triples consistent with Pythagorean relationships.

Mathematical tablets from the Old Babylonian period reveal advanced algebraic reasoning. Written in cuneiform script, they present problems equivalent to modern quadratic equations. Scholars date many of these tablets to approximately 1800 BC. Rather than symbolic notation, problems were described verbally. Solutions involved geometric reasoning tied to land measurement. The base-60 number system enabled precise fractional calculations. Some tablets demonstrate knowledge of what we call the Pythagorean theorem. These were practical tools for surveyors and administrators. Babylonian mathematics was computationally sophisticated despite lacking symbolic algebra.

The administrative state required accurate land assessment for taxation. Mathematical competence therefore had fiscal implications. Survey errors could distort grain quotas and labor obligations. The sexagesimal system also influenced later timekeeping, leaving a legacy in 60-minute hours. Knowledge transmission through scribal schools institutionalized mathematical education. This formal training supported bureaucratic continuity. The empire's stability depended partly on numerical precision. Mathematics became a pillar of governance rather than abstract theory.

For scribes, mastery of mathematics elevated social status. Literacy in cuneiform and number systems created professional identity. Students copied tablets repeatedly, embedding algorithms through repetition. The intellectual labor behind tax calculation rarely appears in heroic narratives, yet it shaped daily life. Farmers experienced its outcomes through measured fields and assessed dues. Ancient algebra determined tangible survival. Behind each harvest stood someone who could divide by sixty.
