In math, a real number is a whole number, a fraction, a negative number, and a number with a decimal. They are considered real numbers because they are not imaginary. A real number is a value that represents a quantity along a continuous line. The adjective real in this context was introduced in the 17th century by Descartes, who distinguished between real and imaginary roots of polynomials.
