* Since in the method of computation adopted we deal with the summations of first and second 
powers of actual measurements, not with their deviations from arbitrary origins chosen to lighten 
computation, we can save materially in the size of the summed products by reducing to half mm, units 
instead of mm. units, i.e. 15 - 0 = 30, 15 - 5 = 31, etc.
