Answer 2

 In 1666 he formulated the binomial theorem, which enabled one to calculate any power of a binomial (an algebraic expression involving two variables being added or subtracted, such as [x + y] or [4y - 7z]) without multiplying the entire expression out. Also in 1666, he discovered how find the slope of a curve at any point on a curve, by a process he called "fluxions." However, while he mentioned the "fluxions" in a letter to Isaac Barrow in 1669, he did not publish the system until 1704, and so must share credit for the innovation with Leibniz, who developed his own method in the 1670s................
