Re: 1/0=0/0=0 example

All,
Saitoh’s claim is wider than 1/0 = 0. It is x/0 = 0 for all real x. Real numbers are a field. The axioms of fields define the multiplicative inverse for every number except zero. Saitoh generalises this inverse to give 0^(-1) = 0. The axioms give the freedom to do this. The really important thing is that the result is zero - a number for which the field axioms hold. So Saitoh’s generalised system is still a field. This makes it attractive for algebraic reasons but, in my view, it is unattractive when dealing with calculus.
There is no milage in declaring Saitoh wrong. The only objections one can make are to usefulness. That is why Saitoh publishes so many notes on the usefulness of his system. I do the same with my system, but my method is to establish usefulness by extending many areas of mathematics and establishing new mathematical results.
