Arrow Arithmetic 1

Age 14 to 16 Challenge Level:

We're in the early stages of developing a useful geometric model of number here.

The aim is to develop geometric analogues of number and number operations.

Ultimately, we'll want to be able to geometrically multiply the geometric analogue of 2 by the geometric analogue of 3 to yield the geometric analogue of 6.

This first idea of using a simple arrow to represent the number 1 needs a little more before it gives us a well defined geometric number.
