comment Calculating quadrant facing from a rotational matrix and two 3d vectors
Since this is a Math Community, rather than a programming one, you'll probably get a better/quicker response by highlighting the mathematical question that needs attention.

comment Number of prime divisors of element orders from character table.
Perhaps a few more words about what Thm. 8.21 in this reference states are helpful. The Question is fairly specific, and while the result there (and proof?) may be spot on, it would surely encourage the Reader contemplating a trip to the library stacks to know more of what is in store.

comment Position n circles in circular layout
If the circles line up as more or less indicated, you have five equally spaced $x$-coordinates and nine equally space $y$-coordinates.

comment What do we mean by derivative of a function? What does it tell?
Possible duplicate of Simple way to understand what derivative is, posed specifically in terms of being unable to follow the Wikipedia page.

comment Functions commute with a given polynomial
You seem to imply commuting with respect to function composition. If so, specifying this would improve the Question and its title.

comment Game idea "square or not"
I don't this kind of "discussion" question is a good fit for Math.SE -- maybe alt.math.recreational would be a better forum. In any case "diagonals bisect one another" is my contribution.

comment Can you use "little" to modify an adjective?
The adverb scarcely would serve in many contexts where you want to convey "not enough" of an attribute.

comment Can you use "little" to modify an adjective?
As hinted at in the last paragraph, the adverb slightly will be serviceable to modify adjectives in many contexts.

I took an educated guess and reformatted the formulas using MathJax. @mr.dont.know , please review and confirm or reproach my effort.
