No, because technically, it is not true.
Because there is no way to define the divisors, the equations cannot be evaluated.
No, but there is a way to prove that zero equals one.
This is a very difficult philosophical question. The best way to look at it is that 2 is defined as 1 plus 1 ! (If it isn't, how do you define 2?)
Yes, it does react in that way.
It is extremely difficult to prove things which are not true.
It does not unless the question is a riddle and has nothing to do with basic arithmetic or if "plus" or "equals" are defined in a non-conventional way.
The right Way
The answer is that there is no such x - unless you define "plus" in some special way.
well it equals 4 any way you put
7-1=6
It would be the same number either way because its addition.
The answer is 37 because 23+37=50
