# Realna števila

> Realna števila vključujejo racionalna in irrationalna števila ter predstavljajo vso številsko premico.

Realna števila vključujejo racionalna in irrationalna števila. Označujemo jih z $\mathbb{R}$.

## Podmnožice

- **Racionalna ($\mathbb{Q}$):** ulomek $p/q$, $q \neq 0$.
- **Irracionalna:** npr. $\sqrt{2}$, $\pi$, $e$.

## Lastnosti

Gostota, neomejenost in zaprtost za osnovne operacije (razen deljenja z 0).

## Zaključek

Realna števila so temelj analize in algebre.
