1. Dividing apples by people: "named numbers"
The First Law of Arithmetic: you do not add fruit and people.
Giuseppe Arcimboldo, Autumn. 1573. Mus´ee du Louvre, Paris.
We have to be careful with "named" numbers and never add apples
I remember asking my teacher why in that case we can divide apples
10 apples : 5 people = 2 apples.
There are two different operations of division:
sharing and dispensing,
they use different data structures!
