comment Counting Rows of a Truth Table that Satisfy a Condition
@Code-Guru Could you please explain the combinatoric method for this specific example in an answer?

@MJD Thank you very much, do keep me posted.

comment Counting Rows of a Truth Table that Satisfy a Condition
I'm looking for a general algorithm, but an approach could help me find the general case myself - I guess I just need some guidance. :)

comment Counting Rows of a Truth Table that Satisfy a Condition
To clarify my last paragraph in the question, I believe I can count rows that satisfy a certain condition - for example the condition $AB$ in a $4$-input function will have $\frac{16}{4}$ rows. My problem is in subtracting the common rows of multiple conditions.

comment Counting Rows of a Truth Table that Satisfy a Condition
Say I have a $64$-input function, I don't want to generate a TT of $2^64$ rows just to count what could probably be counted using a summation.

Thank you for your answer, however I specified I wanted the answer mathematically (ie. no drawing of a truth table). I don't understand why it is impossible - did you read my last paragraph?

comment Finding integer coordinates on a sphere's surface
@GerryMyerson No this subject was discussed in my number theory class. I would also kindly request you stop accusing me of posting PE problems on every question I post.

comment Integer solutions of $p^2 + xp - 6y = \pm1$
Thank you for your answer. Can you explain this part please: "Any positive number congruent to −2 modulo 6"?

@GerryMyerson Yet that question has no answer either.

@Lubin Not necessarily, but it depends on what values of $r$ can generate solutions.

@BillCook That gives points inside a circle, I require points on a surface.

comment Recursive number of divisors function
And this will not work for the number-of-divisors function?

comment Recursive number of divisors function
@GerryMyerson Yes and it didn't work (I tried 72 = 12*6), but I'm sure there must be a similar property since they are both multiplicative functions (I hope so anyway).

comment Recursive number of divisors function
Could this be similar to the totient function which also has this property? Can I also say $\sigma(mn) = \sigma(m) * \sigma(n) * \frac{gcd(mn)}{\sigma(gcd(mn))}$? As per here: en.wikipedia.org/wiki/…

Can you explain the completing the square method in this case? I'm not sure what value I should add and subtract exactly
