'Nullity is a number, and that makes a difference'

'Nullity is a number, and that makes a difference'By Ollie Williams
University of Reading academic Dr James Anderson insists his theory of nullity is 'revolutionary', despite criticism from all quarters following a video report in which he suggested a new means of dividing by zero.

"Nullity is a fixed number with value 0/0," Dr Anderson tells us. "It is not undefined, it is not indeterminate.

"That changes the way you do mathematics - that statement is revolutionary. It remains to be seen whether it is correct or not, whether people accept it or not, but that's my position."

We invited Dr Anderson to the BBC in order to follow up the 1,000-plus comments and criticisms we received in the wake of an article published on 6 December 2006, entitled: '1200-year-old problem "easy"'.
