What is a rational number? Which natural numbers have rational square roots? The decimal representation of irrationals. What is a real number? The necessary numbers are the rationals and irrationals.

In addition to all the fractions, the set of rational numbers includes all the integers, each of which can be written as a quotient with the integer as the numerator and 1 as the denominator.

Is 0/1 a rational or irrational number?

The decimal expansion of a rational number always either terminates after a finite number of digits or begins to repeat the same finite sequence of digits over and over. Moreover, any repeating or terminating decimal represents a rational number. These statements hold true not just for base 10 , but also for any other integer base e. A real number that is not rational is called irrational. The decimal expansion of an irrational number continues without repeating. Since the set of rational numbers is countable , and the set of real numbers is uncountable , almost all real numbers are irrational. Rational numbers together with addition and multiplication form a field which contains the integers and is contained in any field containing the integers.

Math Dr. Math Home What is an integer? It is often useful to think of the integers as points along a 'number line', like this: Note that zero is neither positive nor negative. About integers The terms even and odd only apply to integers; 2. Zero, on the other hand, is even since it is 2 times some integer: it's 2 times 0. To check whether a number is odd, see whether it's one more than some even number: 7 is odd since it's one more than 6, which is even. Again, this lets us talk about whether negative numbers are even and odd: -9 is odd since it's one more than , which is even.
