II. Addition und Subtraktion natürlicher Zahlen:

1. Addieren und Subtrahieren - 2. Rechengesetze und Rechenvorteile - 3. Terme


Erklärung




Hier kannst du das Addieren besser verstehen, indem du mit den Schieberegler die Summanden veränderst.




Und hier kannst du das Subtrahieren besser verstehen, indem du mit den Schieberegler Minuend und Subtrahend veränderst.




  Aufgaben


Bewegt man sich am Zahlenstrahl nach links, so                     man. Bewegt man sich am Zahlenstrahl nach rechts, so                     man. Demnach bewegt man sich bei 5-3 nach                     und bei 5+3 nach                     .
