>>14033728if you mean to say that numbers don't exist, ie, you can't have seven, you can't have zero, then you are correct. You should know however that imaginary numbers are extremely useful, they're the backbone of computing, communications, and signals. I wish you the best of luck building a satellite or even a radio using odd and obscure math instead of complex numbers.
For any brainlets reading, don't think about it too hard. Say you have two kinds of things, and you get a third thing by "adding" those two things together (square both, add them, take the square root). You can measure only one or two of the things easily, so you put a funny symbol (i) in front of one of them to keep them separate.
