+5478 Expanding on Dragonslayer's answer, yes, it is possible to have a negative square root, such as $${\mathtt{\,-\,}}{\sqrt{{\mathtt{4}}}} = -{\mathtt{2}}$$
However, the square root of a negative number does not exist in the real number system, so there is this term called $${i}$$ to express $${\sqrt{-{\mathtt{1}}}}$$. Square roots of negative numbers are expressed in terms of $${i}$$

+8262 Yes. Thank you kitty<3. I tried to get to that point, but I didn't know how to explain it.
