# Tartaglia, Niccoló Fontana (1499–1557)

Niccoló Tartaglia was an Italian mathematician who, with along with Girolamo Cardano,
discovered the algebraic solution of the cubic – an equation of the form *x*^{ 3} + *ax*^{ 2} + *bx* + *d* = 0.
He was also a well-known inventor of mathematical recreations. He devised
many arithmetical problems, and contributed especially to measuring
and weighing problems and to river-crossing
problems. From 1534 he taught in Venice. Although his real name was Niccoló Fontana, he is always referred
to as Tartaglia, "the stammerer." In *Nova Scientia* (1537), Tartaglia applied mathematics to ballistics. Other publications include *Trattato di Numeri et Misure* (1556–60).
