As well-known, Brahmagupta(598年 – 668年?)discovered 0 and established four arithmetic operations on 628 in(ब्राह्मस्फुटसिद्धान्त Brāhmasphuṭasiddhānta)and at the same time he defined as 0/0=0. However, our modern mathematics does not accept the result and we have several opinions as in the attached way. These facts will be our shame: The mysterious history of the division by zero over one thousand years is a great shame of mathematicians and human race on the world history, like the Ptolemaic system (geocentric theory). The division by zero will become a typical symbol of foolish human race with long and unceasing struggles. Future people will realize this fact as a definite common sense.
The division by zero is uniquely and reasonably determined as 1/0=0/0=z/0=0 in the natural extensions of fractions. We have to change our basic ideas for our space and world: http://www.scirp.org/journal/alamt http://dx.doi.org/10.4236/alamt.2016.62007 http://www.ijapm.org/show-63-504-1.html http://www.diogenes.bg/ijam/contents/2014-27-2/9/9.pdf http://okmr.yamatoblog.net/division%20by%20zero/announcement%20326-%20the%20divi
