number that is not an integer)‚ 8.6 (a rational number expressed in decimal representation)‚ and π (3.1415926535...‚ an irrational number). As a subset of the real numbers‚ the integers‚ such as 5‚ express discrete rather than continuous quantities. Complex numbers include real numbers as a special case. Real numbers can be divided into rational numbers‚ such as 42 and −23/129‚ and irrational numbers‚ such as pi and the square root of two. A real number can be given by an infinite decimal representation

The exact values of these irrational numbers cannot be expressed in decimal form‚ and must be left in radical form because the decimal values are rounded and not completely accurate. These irrational radical numbers are called surds. Surds can also be represented in series. In mathematics‚ given an infinite sequence of numbers (an )‚ a series

written as a fraction and as such these are both subsets of rational numbers. Irrational Numbers Numbers that cannot be written as a fraction are called irrational. Example √2‚ √5‚ √7‚ Π. These numbers cannot be written as a fraction so they are irrational. Surds A surd is any number that looks like this √21‚ √15‚ √17. A surd is a root that cannot be written exactly as a decimal or a fraction. They are irrational. Simplifying Surds A surd can be simplified by rewriting the number inside

Although all of Theodorus’ work has been lost‚ Plato put Theodorus into his dialogue Theaetetus‚ which tells the reader of his achievements. It is assumed that Theodorus had proved that all of the square roots of non-square integers from 3 to 17 are irrational by means of the Spiral of Theodorus.[2] Plato quoted Theaetetus speaking to Socrates: It was about the nature of roots. Theodorus was describing them to us and showing that the third root and the fifth root‚ represented by the sides of squares
