A Diophantine equation has elements of this type as coefficients, and a multiplicative inverse element does not always exist for this set, unlike for the reals.
A Diophantine equation has elements of this type as coefficients, and a multiplicative inverse element does not always exist for this set, unlike for the reals. They are the union of the natural numbers, their negatives, and zero, and Kronecker said that "God made [them], all else is the work of man." For ten points, name the subset of the reals that contains all the numbers with no decimal part.
