This is incorrect; in TeX, numbers are not legal parts of a command name.
Hi Pavel, this is on purpose, in order to support names like \frac12. Most, but not all entity names are strict TeX. You can work around this by inserting spaces - \sim2n^2 looks
quite unreadable to me anyway - I would, also in a TeX file, always write it like
\sim 2 n^2
