What kind of number is 0 and 1

Irrational numbers are those real numbers that cannot be represented in the form of a ratio. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero. Whole numbers include natural numbers that begin from 1 onwards , along with 0. Natural numbers are a part of the number system , including all the positive integers from 1 till infinity.

Hence, 0 is also an integer and a whole number, however, it is not a natural number as natural numbers begin from 1 and go till infinity. Is 0 a rational, irrational, natural, whole, integer or real number? This means that they are separate and distinct entities. In fact each of these sets is countable. The last set, R , cannot be counted. This is because they are continuous. Between any two real numbers, however close they may be, there are infinitely more real numbers.

At higher levels of secondary and tertiary education discrete mathematics , is often more challenging than the mathematics of continuous functions. With continuous functions, a small change in the input variable leads to a small change in the output variable. What number times itself equals 2?

But you'll never hit exactly by squaring a fraction or terminating decimal. The square root of 2 is an irrational number, meaning its decimal equivalent goes on forever, with no repeating pattern:.

Other famous irrational numbers are the golden ratio , a number with great importance to biology:. Irrational numbers can be further subdivided into algebraic numbers, which are the solutions of some polynomial equation like 2 and the golden ratio , and transcendental numbers, which are not the solutions of any polynomial equation.

The real numbers is the set of numbers containing all of the rational numbers and all of the irrational numbers. There are infinitely many real numbers just as there are infinitely many numbers in each of the other sets of numbers.

But, it can be proved that the infinity of the real numbers is a bigger infinity. The complex numbers include the set of real numbers. This set is sometimes written as C for short. There are even "bigger" sets of numbers used by mathematicians. The quaternions , discovered by William H. Hamilton in , form a number system with three different imaginary units!
