i think you are talking about the dot product.
(2,2)dot(2,1) = 2*2+2*1=6
you can also write the co-ordinates as
2x+2y and 2x+1y and in this case you can see that it is the x's times the x's and the y's times the y's then all added up.

I don't know if it has a name, but it should be called the Basque method. It was purportedly developed by Basque sheepherders to ward off boredom and keep alert.
