Who was the original discoverer of Calculus?

Answer 1

Newton created it first, but Leibniz created it soon thereafter; however, Leibniz published his work on calculus before Newton.

Answer 2

Calculus was independently discovered by Sir Isaac newton and Gottfried Wilhelm Leibniz in the late 17th century. Newton developed his own system of calculus called "fluxions" and "method of fluents," while Leibniz developed his system of calculus based on differentials and integrals. Both their work laid the foundation for modern calculus.
