If you turn it upside-down, it’s the same (XI+I=X) – which is incorrect. And by turning it upside-down, you are changing it.

Although –

If you hold a mirror in front of it, it becomes correct without changing it. (X=I+IX)

Slack jack,

The equation is “spin 1/2″ symmetric, to both upside down and reflected it will be the same. (X = I + IX)

(X=0, I=0) as well as (X=-2, I=2) would satisfy the equation or make it “correct”….without changing it.

X=1,I=1/2 also works as 1*1/2 + 1/2 = 1

I(i)=(-1) XI+(-1)=X

Imaginary numbers and the whole bit.
