Pythagoras of Samos (c. 570–495 BCE) likely wasn’t the first to find a²+b²=c² — Babylonian tablets from ~1800 BCE used it — but the first rigorous proof is credited to his school.

Step-by-step walkthrough
Apply the formula to a realistic set of inputs: Rows = 6.
- 01Start by noting the input — Rows: 6.
- 02Substitute these values into the formula: a.map(e=>e.join(" ")).join(" | "|
- 03Compute Pascal's triangle: the calculator returns 1 | 1 1 | 1 2 1 | 1 3 3 1 | 1 4 6 4 1 | 1 5 10 10 5 1 | 1 6 15 20 15 6 1.
