comment How Find the diophantine equation $x_{1}x_{2}x_{3}\cdots x_{n}=x_{1}+x_{2}+\cdots +x_{n}$
Why do you think that $f(n)\ge n$? What other triples$(x_1,x_2,x_3)$ satisfy the conditions?

comment Can $x^3+3x^2+1=0$ be solved using high school methods?
+1 very smart. But I think using numbers instead of strange looking symbols for referencing the equations would make a text easier to read.

comment Feedback on my answer for $X^n + Y^n = Z^n $
$$0^3+0^3=0^3$$ $$0^3+1^3=1^3$$ $$1^3+0^3=1^3$$ are solutions. The famous Fermat's Last Theorem states that for $n>2$ there are no solution with positive integers.

comment A question about the minesweeper game
For the $n*1$ board the maximum is $\lceil \frac{n}{2} \rceil$.

comment A question about the minesweeper game
Of course the maximum exists. If you add a bomb to the board the sum will be changed by a value in $\{-8,\ldots,8\}$. So the maximum is less or equal than $8*\text{lengh}*\text{width}$.

I think one understands nothing but will believe everything if one looks at this moving picture. That really is good "1st April" joke.

comment Would like to know which version of inductive formula is better
This question is about syntax and does not depend on any interpretation V. So it is not specific to a 4 valued logic.
