## Description

Real numbers comprise different types of numbers, prominent among them are the rational numbers and the irrational numbers. This course explains the various properties of irrational numbers and how they are linked in the practice of algebra. Are you familiar with the number line system in mathematics? Did you know that all irrational numbers maintain a particular position on the Real number line? Get to learn about the uniqueness of rational and irrational numbers on a real number line. By taking this course, you will get full details on the set of numbers that make up Real numbers. The course will take you through the different evaluation methods for calculating the square root of a number. We have seen in elementary mathematics that finding the square root of a perfect square can be quite easy. But, when the radicand is not a perfect square, there are proven and tested methods that can be used to find the approximate value of the square root. The course will take you through the approaches employed by mathematicians in finding the square of perfect squares.
