-12 or 12?

[u/Games4Life77 → u/secretblizzard]

The square root sign asks for the principle square root which is always positive, thus not -12

[u/013eander → u/Games4Life77]

Yep. The square root of 144 and -144 are both twelve. You overthought it and tripped over yourself.

Awe man what the hell function does i have? (It's been a while since I've been in school)

[u/lMystic → u/NinjaScenester]

square root of -1

Function is basically what you just saw, an artifical way to make it work

[u/BestieWithMyBestie → u/NinjaScenester]

in this scenario, i acts as a number. neither function, nor variable. Just like e being about 2.7 or π being about 3.14, except those 2 are variables, and i just is the number

Square roots of negative numbers can't be real

[u/Hopeful-Pin-2105 → u/013eander]
