In the nineteen sixties, Abraham Robinson confirmed how infinitely big and infinitesimal numbers might be rigorously outlined and accustomed to develop the sphere of nonstandard analysis. The procedure of hyperreal numbers represents a arduous means of dealing with the ideas about infinite and infinitesimal numbers that were utilized casually by mathematicians, researchers, and engineers at any time For the reason that creation of infinitesimal calculus by Newton and Leibniz.
The answer in the equation x2 + a = 0 is just x = ±√-a, which in historical periods was not recognized as the solution given that they didn’t know any these kinds of number whose square was a damaging quantity, but at some point, some mathematicians began utilizing this kind of variety and saw that this built feeling for plenty of other calculations as well.
