 Apr16 awarded Fanatic Apr11 answered what is the best way to win: every 1000 submission will win Mar20 answered What's the difference between tuples and sequences? Feb22 comment Examples of apparent patterns that eventually fail @Peter not to mention that (with E a number of even kind and O of odd kind) E*E=E E*O=O O*E=O and O*O=E (just like with addition and normal odd/even in terms of mod 2) which would result in 1 being of even kind so that E*1=E and O*1=O Feb22 comment Examples of apparent patterns that eventually fail @phkahler if you go by the fact that $1$ is not a prime then $1$ is of even kind because it has $0$ prime factors (and last I checked $0$ is even) Feb10 revised Locally Bounded Functional Equation $f(x+y) = f(x) + f(y)$ and Continuity added 3 characters in body Feb10 answered Locally Bounded Functional Equation $f(x+y) = f(x) + f(y)$ and Continuity Jan30 comment Pythagorean Theorem Proof Without Words (request for words) congruent triangles at least there's a right angle and the respective adjoining it sides are equal lengths Jan29 answered Pythagorean Theorem Proof Without Words (request for words) Jan29 comment Which of the numbers $99^{100}$ and $100^{99}$ is the larger one? @RobertIsrael if you say $x,y \in \mathbb{N}$ then $x>2$ suffices Jan28 comment Which of the numbers $99^{100}$ and $100^{99}$ is the larger one? it holds when $x>2$ Jan23 comment Base ten is called “decimal”; what's the name of numbers in base 15? it has no real name you could expand the latin (or was it greek?) to other numbers (pentadecimal) but I doubt it will catch on, no-one uses base 15 or base 9 enough for it to get a name Jan19 answered Finding location of a point on 2D plane, given the distances to three other know points Jan18 awarded Supporter Jan18 comment logical question: prove that a number is divisible by 6 with the exception of $x-1=3$ ofcourse ;) Jan13 comment Algorithm for computing powers @hydroparadise the only hard function here is the mult, the div and mod functions here can be easily done with masks and shifts (it's always divide/mod by 2) Jan4 comment Cycle attack on RSA wouldn't that mean that $e^k \mod \phi(n) = d$ Dec22 awarded Citizen Patrol Dec19 answered point of an equilateral triangle Dec18 answered Rotating a point in three-dimensions so that it falls along the X-, Y-, or Z-axis
