comment Coordinate vector of a subspace of $\mathbb{M}_{2,2}(\mathbb{R})$
@user156384: No. It may have been an error I guess. Just curious if perhaps there were multiple coordinate vectors (can there be?)

comment What to do with a hanging $1$ in a Karnaugh map?
@tpb261: Would it still be correct if I didn't group it with another $1$?

comment 'Obvious' theorems that are actually false
@MJD: If you keep expanding the surface area of the clay, won't it reach a point in which the distance between the atoms is great enough causing the clay to disintegrate? If that was the case, you shouldn't be able to expand a clay's surface area infinitely (I dunno, I'm no mathematician).

@DanielY: Well, yeah, no reason in particular. I just used the permutations formula. I think it's the same thing?

comment Creating digit sequences that can't begin with $0$, but one digit must repeat exactly once.
@RossMillikan: I see. So if the question meant that the two repeated digit must be together, I would apply Bananarama's answer?
