What is real number
What is real number Real numbers are nothing but numbers that include both rational and irrational numbers, in other word the combination of rational and irrational numbers . Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers. In mathematics, real numbers are a set of numbers that include both rational and irrational numbers. Real numbers can be represented on a number line and are used to describe quantities that can be measured or expressed as decimal numbers. Real numbers include whole numbers (such as 0, 1, 2, 3, etc.), integers (such as -3, -2, -1, 0, 1, 2, 3, etc.), rational numbers (such as fractions or decimals that can be expressed as a ratio of two integers, like 1/2 or 0.75), and irrational numbers (such as π or the square root of 2, which cannot be expressed as a fraction and have non-terminating or non-repeating decimal expansions). The set of real numbers is denoted by the symbol ℝ.
