 Oct 28 comment Is there any closed form solution for a function $f$ on $\mathbb R$ satisfying $f(t+s)=f(t)f(s)$ The constant $1$ is also an exponential function: $1 = \exp(0x)$. Oct 27 comment The law of the unconscious statistician Maybe it's because if you're unconscious, you don't have any expectations (in the usual, psychological sense). Oct 26 comment Relatively tight upper and lower bounds for surreal numbers Great, thank you. Of course when you say "of unbounded birthdates" you mean "unbounded in $\mathbb N$", as all birth dates of dyadic fractions are bounded by $\omega$.

Oct 25 revised Another way of counting probability Corrected for the condition that at least one number has to be chosen Oct 25 comment Another way of counting probability @paw88789: Ah right, I overlooked that condition. But the claim that all possible sets are chosen with equal probability should still be sufficient. I'll rework the answer.

This implies that he (a) doesn't gain solutions (he does), and (b) he loses solutions (he doesn't). Oct 24 comment What does $\frac{dx}{dx}=1$ mean? @E.A.Shams: I've now updated my answer.

Indeed, $x$ changes by exactly the value by which you change $x$, so the quotient of both changes is obviously $1$.
