## 'Arrow Arithmetic 1' printed from http://nrich.maths.org/

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.
