It seems that we humans top of food chain cant still perfectly understand the zero, the real problem with zero is it is an unusual number how ever it is said that every number is unique but every one of us know zero is just a number we do not want to mess with coming to the actual problem there are two theory’s old and new
Old theory:-
the old theory says anything divided by zero is infinity
example :-1/0=∞
this conclusion is give by Indian Mathematician’s Brahmagupta, he arrived to this conclusion from fallowing experiment
He took a number and divided it with number’s near to zero
example:- 1/0.1=10 i.e there are 10 number of 0.1 in 1 so 0.1*10=1
1/0.01=100 there are 100 0.1 in 1 so 0.01*100=1
1/0.001=1000 . . .
he finally concluded that a Natural numbers is sum of infinity fraction so when any number divided by zero all those infinity fraction come out so he said any thing divided by zero is infinity
New theory:-
later another theory came taking the same example but negative numbers
-1/0.1=-10
-1/0.01=-100
-1/0.001=-1000
so they concluded it as negative numbers divided by zero=-∞
so we got functions like
how ever this all leads to confusion and does not solve 0/0
more over if 1/0=∞ and 8/0= ∞ that makes 1=8 in this way it effects uniqueness of every number it seems that all numbers are same in this way and more over ∞ is just a idea not a accurate value or anything we are close to know
so present day mathematicians to avoid all this confusion made any thing divided by zero is undefined
