Yeah... it depends on how much math the person you are talking to knows:

sqrt(-9) = No real answer: if you don't know complex numbers exist
sqrt(-9) = 3i : If you watch some guy on the internet
sqrt(-9) = 3i and -3i: If you actually care about math at all...

100% agree!

If it breaks Russell and Euler it’s wrong. I stopped flying partly because of this quick change to our OOO which people haven’t been notified of.
