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.

Yeah, square root implies absolute numbers. You need to manually multiply by -1 to get the other solution to x^2

So close yet so far. If only you head read ONE more paragraph.
Every nonnegative real number x has a unique nonnegative square root, called the principal square root or simply the square root (with a definite article, see below), which is denoted by √x where the symbol "√" is called the radical sign or radix.

I once tried to start a conversation with a girl at a party, but she immediately said she had a boyfriend and pointed at him.
So I had a great, long talk with her boyfriend the whole evening, drinking beers, making jokes and laughing hysterically, while the girl stood in the corner by herself with a glass of water, looking pissed, car keys dangling from her finger.What a great night.

I’m going to go with “what is a story that started out real but you made up the end in your head on your way home?”

Why is it millennials that "ruined" it in your opinion ? I assumed it disappeared because everybody has mobile phone with a clock on it.

Yeah it's definitely due to phones, I was only joking about millenials. Seems like something the news would say.

Millenials destroyed the spacetime continuum in 2168 after trying to make a fidget spinner out of black holes.

Look at the inverse of the square root function, f(x)=x² (https://www.desmos.com/calculator/2v5gzbhru8)
You can get the sqrt of a given x by looking at the y axis. E.g. the value of y=4 has two solutions, x=2 and x=-2. This however does not mean that the sqrt of -4 is also 2! If you look at graph you can see that there are no solutions for y less than 0.
sqrt(-1) , sqrt(-2) (i ill omit imaginary numbers here) and so on do not have a solution. There is nothing you can replace with such that x × x is < 0 because multiplying two negatives always nets a positive.

I really don't like the sqrt shorthand.
They knew.

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 and the number called square root; I've edited my comment. Thanks for correcting me!

Yeah, I see how that can happen. Very confusing to have the same name for two things differentiated only by the use of a definite or indefinite article.
