Classifying real numbers

The video tutorial explains how to classify numbers, focusing on the number -7. It begins by categorizing numbers into real, rational, and irrational. Rational numbers are those that can be expressed as fractions, while irrational numbers cannot be precisely written down, like Pi and sqrt 8. The tutorial then explores integers, which are rational numbers that can be negative, and whole numbers, which are non-negative integers. Natural numbers are introduced as positive whole numbers excluding zero. Finally, -7 is classified as a real, rational, and integer number.
