Real Numbers: Irrational Numbers

The video tutorial explains the difference between rational and irrational numbers, providing examples of each. It discusses how integers, terminating decimals, and non-terminating repeating decimals are rational numbers. The video also covers irrational numbers, which are non-terminating and non-repeating decimals, and provides a mathematical proof that the square root of 2 is irrational. Additionally, it highlights the properties of irrational numbers, such as their behavior when added, subtracted, or multiplied with rational numbers.
