comment Why not write $\sqrt{3}2$?
@ThomasAndrews there's also $x_2$ to confuse it with especially when you pronounce $x_2$ as "ecks two"

comment Where's the problem in this equation? Resulting in $4 = 5$
you could try to solve the left and right side on each line and see where it starts to differ

comment Big O Notation reliability?
it's still wrong $100=10^2$ so $a$ should be equal to $2$ not $100$

comment Big O Notation reliability?
how do you get from $1=\frac{n^{0.001}}{100}$ to $n=10^\frac{100}{0.001}$?

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

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)

congruent triangles at least there's a right angle and the respective adjoining it sides are equal lengths

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

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
