Classifying real numbers

The video tutorial explains how to classify real numbers into rational and irrational categories. It begins by introducing real numbers and their classification. Rational numbers are defined as numbers that can be expressed as fractions, while irrational numbers cannot be precisely written as fractions due to their non-repeating, non-terminating decimal nature. Examples such as pi and the square root of 7 are used to illustrate irrational numbers. The tutorial concludes with a practical example, demonstrating that the square root of 260 divided by 2 is an irrational number.
