The most commonly featured mathematical tablet is **YBC 7289** (Yale Babylonian Collection), an Old Babylonian student exercise showing a square with its two diagonals. Along one side is the sexagesimal number 30; along the diagonal is 1,24,51,10 — that is, 1 + 24/60 + 51/3600 + 10/216000 ≈ 1.41421296, the square root of 2 correct to six decimal places. The scribe obtained this by an iterative approximation, not by a formula for √2. This is genuine, spectacular mathematics.
