Ordinal numbers give us the precise placement of a factor, item, or an object inside the listing. Ordinal numbers inform the place of the item rather than its amount.
For a protracted period of time, persons assumed the amount program was incomplete and necessary some new type of numbers to accomplish it, as there was no Resolution to your equation x2+a=0(in which a>0) in true numbers, but we now know by the fundamental theorem of algebra that each polynomial of degree n must have n roots. So there has to be a different sort of amount necessary to locate the solution to the above equation.
