Analysis 1 | Intervals, subsets, and Archimedean property - Properties of Sets (1.2)
Build the intervals and stay inside Whenever I talk about mathematics, I directly think of number sets. It is surprisingly hard to build, yet easy to understand. Each of them have a different purpose, there is a very close relation between them. Until we prove the properties and maybe the existence of the number sets we will use $\mathbb{R}, \ \mathbb{N}, \ \mathbb{Z}, \ \mathbb{Q}, \ \mathbb{C}$ without proving the properties, as if we all accept and embrace them. Further, Even I won’t talk about Peano’s axioms. ...
