The product of a non-zero rational number is
WebbAny two rational numbers can be written and , where are integers, and and are not zero. The sum of and is . The denominator is not zero because neither nor is zero. Multiplying or adding two integers always gives an integer, so we know that and are all integers. If the numerator and denominator of are integers, then the number is a fraction ... WebbExamples. As an example, the field of real numbers is not algebraically closed, because the polynomial equation + = has no solution in real numbers, even though all its coefficients (1 and 0) are real. The same argument proves that no subfield of the real field is algebraically closed; in particular, the field of rational numbers is not algebraically closed.
