Alles rechnen ist ein Operieren met Zahlen.
Die Rechnungsarten sind die verschiedene Operationsmögligkeiten,
denen die Zahlen unterworfen werden können. Wie steht es dabei nun aber mit den Zahlen selber
die doch erst die Voraussetzung für alles Rechnen abgeben?
Bevor man überhaupt zu rechnen beginnt, muß mann zum Erlebnis der Zahl als solcher gebracht werden.
z.B. Die Grimmschen Märchensammlungen, die erstaunlich reichhaltig von dem Vorkommen bestimmter
Zahlen zu berichten wissen, können dabei zu statten kommen.
