I Numeri Interi Relativi

Immagina la matematica come un termometro: non ci sono solo i gradi sopra lo zero, ma anche quelli sotto! I numeri interi relativi sono esattamente questo - tutti i numeri con il segno + o - davanti.

Quando li rappresenti sulla retta orientata, lo zero sta al centro, i positivi vanno a destra e i negativi a sinistra. Più vai a sinistra, più i numeri diventano piccoli (come quando fa più freddo!).

Ci sono tre tipi di relazioni tra questi numeri che devi assolutamente ricordare:

  • Opposti: stessi numeri ma segni diversi come14e+14come -14 e +14
  • Concordi: numeri diversi con lo stesso segno +20e+14+20 e +14
  • Discordi: numeri diversi con segni diversi +20e16+20 e -16

Il valore assoluto (scritto con le barrette |+2|) è semplicemente il numero senza segno. Facile, no?

💡 Trucco: Per ordinare i numeri, pensa al termometro - più vai verso i positivi, più "caldo" diventa!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I numeri interi relativi sono tutti i numeri che conosci (positivi e negativi) con il segno davanti. È un argomento fondamentale che ti servirà in tutta la matematica, dalle equazioni alle funzioni!
