I assume you’re nerd baiting* with that, but it’s infuriating how many math teachers actually teach that.
It’s not that complicated. x² = n isn’t the same thing as x = √2 because then square rooting isn’t a function, which is asinine. (Similarly to why 0! isn’t defined to be 0, because otherwise it’s a stupid notation that would need a piecewise function definition for just about every single application of the factorial function.)

Edit: my phone autocorrected “isn’t” to “is”, lol.
Nah, dog. You’re arbitrarily ignoring negatives. The square root of 4 is ±2.Nah, dog. I’m wrong

I guess that’s what I was thinking. I don’t think I can even blame my math teachers.
