1st type of 0 is for making numbers like 1_0, 2_0, 3_0, 1_00 etc
2nd type of 0 is for separating 1 from -1. This zero doesn’t exist.
Cos 2nd type of zero separates 1 from -1 it is 0 = point of crossing of coordinate axices.
There are no X, Y or Z in nature, cos there’s no space between 50 and 51 in 100%. X, Y and Z should be called “not existing separators”.
In nature things are connected without zero of the second type = without “not existing separators”. So there’s no point to write -1, 0, +1. In nature it’s -1, +1.
Like in Mirror Universe there’s no mirror glass, no zero. and there is no time too.
So zero is a myth.
