The Square Root of Negative Two Is a Real Number, Right?

My favorite example of, it's also a mathematical example of real from Lacan is the square root of negative one. So within, and this is the whole, the problem is the language becomes complicated, right? Because it overlaps with his language in ways that are not exactly correct. But so in the, in the set of all real numbers, the squareroot of negative one doesn't exist. It ends up being an imaginary number. The inability to have a symbolic answer to that is the real, and yet that's an operation you can perform within the mathematical universe of real numbers. I think he would be the way to put that on further.
