comment Boy Born on a Tuesday - is it just a language trick?
@muad: there doesn't seem a mistake in your derivation; the error was in my intuition that the day couldn't possibly have anything to do with it.

comment Do complex numbers really exist?
"When you first hear this, it sounds crazy." I must say, when I first saw it being drawn in the Argand plane, it made perfectly sense to me: you introduce an imaginary axis because your imaginary number obviously can fit nowhere on the real axis. If you say i = 1 rotated CW over 90°, then i*i = 1 rotated over 2*90°, and you've arrived at -1, back on the real axis! The Argand plane made it all clear to me. Unfortunately I have no such representation for quaternions :-(

comment Liouville's number revisited
I guess I should have said "Liouville's constant" instead of "Liouville's number".

comment We can divide $7^{17} - 7^{15}$ by?
I hope this was a multiple choice question, because 6 is not the only answer. There's 1, 2, 3, 4, 6, 7, 8, 12, etcetera. 160 divisors in all :-)

comment We can divide $7^{17} - 7^{15}$ by?
7^17 - 7^15 = 7^2 * 7^15 - 1 * 7^15 = (7^2 - 1) * 7^15

7^17 - 7^15 = (7^2 - 1) * 7^15 = (49 - 1) * 7^15 = 48 * 7^15. No division required.

comment Collinear points theorem
@moron: No I hadn't tried it first, but at least it looks like I'm pretty good at choosing a title for my question! :-) Thanks for the link. +1
