Final answer:
Plimpton 322 is an ancient Babylonian tablet that contains mathematical formulas and equations, particularly Pythagorean triples.
Step-by-step explanation:
Plimpton 322 contains mathematical formulas and equations. It is an ancient Babylonian tablet that has intrigued mathematicians and historians alike because of its sophisticated understanding of Pythagorean triples, which are sets of three integers a, b, and c that satisfy the condition a2 + b2 = c2. This suggests the Babylonians had knowledge of right-triangle geometry over a millennium before Pythagoras and Euclid. The tablet serves as a historical artifact, demonstrating the impressive mathematical achievements of ancient civilizations.
