Any number on the number line
Real numbers are a set of numbers that includes all the rational and irrational numbers. Rational numbers are numbers that can be expressed as a ratio of two integers such as fractions and decimals that terminate or repeat. Irrational numbers cannot be expressed as a ratio of two integers and their decimal representations continue infinitely without repeating.
Examples of real numbers include:
– Integers such as 0, 1, 2, -3, -100
– Fractions such as ½, ¾, -2/3
– Decimals such as 0.5, 1.234, -3.14159…
– Irrational numbers such as √2, π, e, √3
Real numbers are important in mathematics as they are used in various mathematical operations such as addition, subtraction, multiplication, and division, and they have many applications in various fields, including science, engineering, and finance.
