![]() They are also called ‘counting numbers’ or ‘natural numbers’. Mark an equal length on both sides of the origin and label it with a definite scale. Whole numbers are positive integers, beginning at zero and stretching to infinity.Draw a horizontal line with arrows on both ends and mark the number 0 in the middle.Real numbers can be represented on a number line by following the steps given below: A rational number includes positive and negative integers, fractions, like, -2, 0, -4, 2/6, 4.51, whereas, irrational numbers include the square roots of rational numbers, cube roots of rational numbers, etc., such as √2, -√8 How to Represent Real Numbers on Number Line? ![]() ![]() The integers are represented by the symbol ‘ Z’. Integers is a special set of numbers comprising zero, positive numbers and negative numbers. Real numbers can be classified into two types, rational numbers and irrational numbers. The word integer originated from the Latin word Integer which means whole or intact. In other words, the numbers that are neither rational nor irrational, are non-real numbers. The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers ( \(\overlineĬomplex numbers, like √-1, are not real numbers. These numbers include the set of complex numbers, C. We then choose some convenient length, and moving to the right, mark off consecutive intervals. To construct a number line, we simply draw a straight line and choose any point on the line and label it 0. Now, which numbers are not real numbers? The numbers that are neither rational nor irrational are non-real numbers, like, √-1, 2 + 3i, and -i. Whole numbers may be visualized by constructing a number line. Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers. For example, 3, 0, 1.5, 3/2, √5, and so on are real numbers. Any number that we can think of, except complex numbers, is a real number.
