In math I learned how to classify real numbers, determining the classification of all numbers, and applying the density property of real numbers. Learning how to classify real numbers, determining the classification of all numbers, and applying the density property of real numbers was hard, but once I figured it out it got a lot easier. You had to learn what was number was a real number or not real, you had to find out if something was rational or irrational, if something was whole, and integer. I understood rational and irrational, but i didn’t understand what a whole and a integer was. As I kept doing it over and over I figured out how to do it.
