comment 4 tables or 4 table?
The "tables" answers are probably right. But I can imagine there is a table called "the 4 table" (because this table is somehow based on the number or shape "4"). Then you could, indeed, deal with the 4 table.

+1. Only flabby99 can tell us if this problem is in his textbook after a discussion of the Chinese Remainder Theorem.

comment How does atan(1) * 4 equal PI?
But in both these cases you must make sure you are in radian mode, not degree. The arctan of 1 is 45 degrees.

comment How did Gauss become the "the prince of mathematicians"?
+1 for this. I had guessed that "Prince of Mathematicians" was hyperbole originated by E. T. Bell.

comment How did Gauss become the "the prince of mathematicians"?
Gauss the mathematician may be not well-known outside mathematics. I once surprised an astronomer by saying Gauss was a mathematician; he thought Gauss was an astronomer.

@Danu: Gauss, the prince of mathematicians; Euler, the master of us all. What others have such grandiose handles?

comment $X$ is Frechet Compact iff $X$ is compact.
Looked it up (nonstandard terminology). Frechet compact means every infinite subset has a limit point. Also: these are not true for topological spaces, perhaps you mean this to be for metric spaces.

Refrain from correcting formatting that is a matter of opinion. Do not change $dx$ to $\mathrm{d}x$, or vice versa, for example.

comment A Logarithm Integral II
for example, for $m=1,k=5$ we get $$\frac{120445}{1944}-40\left(\frac{\zeta(2)}{81}+\frac{\zeta(3)}{27}+ \frac{\zeta(4)}{9}+\frac{\zeta(5)}{3}+\zeta(6)\right)$$

comment why is the domain of the function in the picture >=0, why is it not just !=0
Since Wolfram works with complex numbers by default, and uses the "prinicpal" value for powers, it turns out that an odd root of a negative number is a non-real complex number.
