  This can be expressed in the form of an integer divided by an integral.

  You saw that all rational numbers have decimal forms that are either terminating or recurring, and so the following number is not a rational number.

The measure the length, you 1^st need to decide on unit of measure. The unit can be a centimetre, a meter, and or any other conveniently does not matter what it is, as long as it is used consistently.

Suppose that redesign to measure licensing centimetres. Here is the ransom some lines measured using this unit. Consider the diagonal winds in the tiling pattern. The pattern is made up all square tiles, each with 1 cm long and each tail is half green and half yellow.

 The diagonal line from the sides the green square. So the length of the sides of the green square, measured in centimetres is not a rational number.

 This is true no matter what unit of measurement. You choose. Of course, in practice, you can approximate these lines by rational numbers, but a sensible system of numbers should include the numbers that are the exact length of these lines stop so the rational numbers by themselves, do not form a workable system of numbers. We must include the decimal with an infinite number of digits after the decimal point, but no repeating block of digits. These numbers are called the irrational numbers. They are the numbers that are not rational.

 The irrational numbers also include the positive number is square is 3, which is denoted by square root of 3, and many other age irrational numbers. Number irrational number is pie.

This is an important number in mathematics, and you will see you use frequently in some of the lighter units in the module, stop. There is nothing special about this one, except that its digits have a pattern, one that is different from the type of past and found in the decimal form of rational numbers.

  Your irrational numbers, together with the rational number from the real numbers. These numbers are significant to represent the length of any line or curve. Each point on the number line represents a real number, so the number line is often called the real-line.

There are infinity men irrational numbers and infinitives make many irrational numbers stop

 complex numbers include all the numbers above and also many imaginary numbers, searches the square root of -1. The idea of imaginary numbers might seem strange, but the complex numbers have a huge number of useful practical applications stop
