    This sentence made no sense to me as it directly contradicted the previous one. But it’s just a confusion on my part between the function called square root, which confusingly outputs two different numbers called “square roots”, and “the” number called square root; I’ve edited my comment. Thanks for correcting me!

    No?

    In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16 because 4² = ( − 4 )² = 16.

    Wikipedia


    Edit: I’m wrong lol, there is a difference between the square root function, which accepts two results, and the square root, or principal square root, which is a unique positive number
