+ your idea in favour of below is welcome

about zero

  initialy there was develop  relations/pairing  inbetween objects and then transaction.number symbol for trans action

after that   symbol for how much + addition .perhaps frequency of in transaction that is transction in transaction begates substration - processs.  this substraction process begets symbol 0 zero. in positive number/natural number  there is no roll of 0. the rule of  substraction/division was defined before zero. in natural number there is no question about zero divides any natural number or divible by  any number.substraction divisionin between two numbers a,b occurrs if and only if a>bthat is a=bq+r    where     r<b

that is why wesay 0 is not defined.

0does not take part in division how we can say/think that zero has factor/divisible. zero is or notcan not explain in natural numb
