We don't add two numbers since \sqrt{i} is not a number because this notation is a nonsense ! Can you read carefully what I wrote ???

 It seems to work just fine in wolfram alpha (desmos in complex mode gives the same answer).

The fact that online tools give an answer is not a proof.
These tools are made to give an answer to almost everything. I bet you could not find any research paper using this notation. Same as \sqrt{-1} which is never used.
