Answer:
He argued that mathematics could be used to measure and describe all motion in the universe.
Step-by-step explanation:
Newton developed a mathematical model that explained, measured and described motion. He developed calculus to prove it, but he published it in a more classical mathematical way because calculus was little understood in his time.
Newton's laws of motion and his formulation of gravity were a breakthrough at the time. The mathematical model allowed other scientist and engineers to precisely calculate and predict motion, heat, the orbits of the planets, etc.
