Irrational Numbers

The video tutorial explains the classification of numbers into whole numbers, integers, rational numbers, and irrational numbers. It highlights that whole numbers and integers are subsets of rational numbers, which can be expressed as fractions. The video introduces pi as an example of an irrational number, which cannot be expressed as a fraction and has a non-repeating, non-terminating decimal. The lesson concludes with a focus on irrational numbers and hints at further exploration in future lessons.
