# Breuken optellen en aftrekken

> Leer breuken met gelijke en ongelijke noemers optellen en aftrekken.

## BREUKEN BEWERKEN

Om breuken op te tellen of af te trekken moeten ze dezelfde noemer hebben. Bij gelijke noemers tel je de tellers op of trek je ze af.

Bij verschillende noemers zoek je eerst een gemeenschappelijke noemer. Vereenvoudig het resultaat daarna zo ver mogelijk.

## CONCLUSIE

Een vaste werkwijze voorkomt fouten bij bewerkingen met breuken.
