| Jul 20, 2023 at 20:45 | comment | added | Joel David Hamkins | @SebbyIsSwag The Conway game notation realizes surreal numbers as Conway games (which simply drop the requirement that members of the left set must be less than members of the right set). And those games have a kind of algebra. To my way of thinking, the question would be: can we realize the surreal complex numbers in the space of Conway games? For example, which game is the imaginary unit $i$? Your proposed representation does provides a notation for the surreal complex numbers, but not as Conway games. | |

TeX note: $No$ No spaces poorly. If you want something similar looking, you can use $\mathit{No}$ \mathit{No}; I edited accordingly. If you would like it upright, as in @JoelDavidHamkins's answer, then you can use $\mathrm{No}$ \mathrm{No} (but note that \operatorname is often the better tool for upright mathematics—it is meant, as the name suggests, for "operators", like $\sin$, $\cos$, $\lim$, etc).
