comment Historical (personal) examples of teaching-based research
This question is not a million miles removed from one I asked here, mathoverflow.net/questions/39061/…

comment Avoiding Fibonacci-like sequences
I think if you search for "sum-free sets" you'll find a lot of work on these. Alternatively, figure out the first few terms, and look it up in the OEIS.

comment Need a calculator to evaluate function at irregular input values
Wrong site --- we do questions of math research here at MO.

comment Roots of 3 polynomials in two variables in terms of the coefficients
"Unclear what you're asking"? Two polynomials in one variable do not have a common zero if the determinant of the Sylvester matrix is not zero. Isn't it clear that OP is asking whether there's anything like the Sylvester matrix for three polynomials in two variables?

comment Is there an algorithm to solve quadratic Diophantine equations?
@Turbo, on the cited page of Garey & Johnson, they say "Transformation from 3SAT."

comment Is there an algorithm to solve quadratic Diophantine equations?
@Turbo, have you had a look at the Manders & Adleman paper?

comment Prize allocation of scratch codes to ensure correct number of prizes to give away
MO is for questions of math research (as you might have been able to work out for yourself).

You might want to provide a link to some place where we can see what $8_{19}$ is.

comment What is the status on questions related to Bhargava's factorial function?
The paper was published: Bhargava, Manjul, The factorial function and generalizations, Amer. Math. Monthly 107 (2000), no. 9, 783–799, MR1792411 (2002d:05002). The review mentions 5 citations in other reviews, and 30 citations in references in other reviews. If you have access to Math Reviews, tracking those down should keep you busy. . .

comment What is the status on questions related to Bhargava's factorial function?
What does "find $a_1$ giving the smallest power of $(a_1-a_0)$" mean? [and why would this question get migrated away from math.stackexchange?]

comment Does this inequality always hold?
This clarification should be edited into the body of the question, so people don't have to go searching the comments to find it, liuchun.

Is there a simple example where you get $\pi/3$?

comment Uninteresting questions with interesting answers
@Todd, what I meant was, by our upvotes and downvotes on answers, users are deciding deciding which questions are uninteresting. "How many primes are there" is currently at minus 2; the voters seem to agree that that question is not uninteresting. Joe Silverman's answer is at plus 33; the voters seem to agree that that question is uninteresting. It might be somewhat subjective, but there's also a fair bit of agreement here.

@Todd, you could always let the voters decide which questions are uninteresting.
