'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
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
