Real numbers are a fundamental concept in mathematics, representing all the numbers on the number line, including both rational and irrational numbers. Rational numbers are those that can be expressed as the ratio of two integers, such as 3/4 or 22/7. Irrational numbers, on the other hand, cannot be expressed as a ratio of integers and have decimal expansions that go on indefinitely, like pi (3.14159...). Real numbers are used in various mathematical operations, including addition, subtraction, multiplication, and division, and are essential in algebra, geometry, and calculus.
