comment About an orthogonal complement theorem
@JulianP: You're right! I guess that's the problem?

comment Coordinate vector of a subspace of $\mathbb{M}_{2,2}(\mathbb{R})$
@user84413: I'm sorry, I didn't know that. I have added the basis. $\left\{ \left ( \begin{matrix} 1 & 0 \\ 0 & 1 \end{matrix}\right ) , \left ( \begin{matrix} 0 & 1 \\ 1 & 1 \end{matrix} \right )\right \}$

@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).

comment Creating groups with 10 men and 10 women.
Thank you, I think the formula in the first one confuses me. What is the logic behind it exactly? (Yeah I just used the same formula in the third question without knowing why)

@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?
