. We're sorry about the hassle.
you mean 0 is a complex number, then 2=2+0i is also a complex number , then each real number is an imaginary number, but i may be wrong , i don't know much about complex numbers

All Real numbers are Complex number since Real number is a subset of Complex Number
There is a difference between complex numbers and imaginary numbers. Imaginary numbers are of the form i ⋅ a where a ∈ R , whereas complex numbers are of the form a + i b where a , b ∈ R .
Well actually real numbers are a subset of complex numbers. Your illustration is nice.
substitute x for 1+i , and the answer would be 2 , so the statement is disproved
1 + i 1 = 2 1 − i ( 1 + i ) × 2 1 − i = 2 2 = 1

Since 0 = 0 + 0i ---> 0 is a complex number. If x = 0, then x(1/x) = indeterminate
