Therefore, its a non real complex number.
2 -  =
 = 
                = 
                =  
 
This number is a Non real complex number.

               = 18i
It's a non real complex number.
3 + 2i 
It's a non real complex number.
-289 
It's a purely real number.

              = 4 + 32
              = 36
