Is every natural number a real number
WebMethod 3: Again, suppose that x y = y for all real y. Put another way, x y − y = 0 for all real y, or by factoring, ( x − 1) y = 0 for all real y. Now, the only way two real numbers can have a product of 0 is if at least one of the numbers is 0, so we know that x − 1 = 0 or y = 0. ( Note: This includes the possibility that both are 0.) WebThe natural numbers are, of course, also called the counting numbers.
