>>8055305because otherwise the notation would be retarded.
how would you denote the positive square root of 4 , +√ 4?, that looks retarded then if you wanted to add the positive square root of 4 with x then it would be x ++√ 4 what the actual fuck, if it gave two answers then it wouldn't be a function which is pretty cringe
It's much better to denote the positive sqrt of 4 as √4 the negative √4 as -√4 and plus or minus sqrt 4 as ±√4.
