## What are Real Numbers?

Real numbers are numbers that can be used for counting, measuring, and solving problems. They include whole numbers, such as 1, 2, 3, 4, and 5; fractions, such as 1/2, 1/4, 1/8, and 1/16; irrational numbers, such as the square root of 2; and the number zero. Real numbers can be represented by symbols, such as the number zero being written as 0, or the fraction 1/2 being written as 0.5.

## Types of Real Numbers

The types of real numbers include natural numbers, integers, rational numbers, irrational numbers, and complex numbers. Natural numbers are the counting numbers, such as 1, 2, 3, 4, 5, and so on. Integers are whole numbers, including negative numbers, such as -1, -2, -3, and so on. Rational numbers are fractions, such as 1/2, 3/4, and so on. Irrational numbers are numbers that cannot be expressed as a fraction, such as the square root of 2. Complex numbers are numbers that are the sum of two or more real numbers, such as 3 + 4i, where i is the imaginary unit.
