comment Can $x^3+3x^2+1=0$ be solved using high school methods?
If it gives the answer as an approximation this makes me wonder if this was one of the questions where they ask you essentially to just graph it and look at the plot to find an approximate solution. I recall having a few like that in high school...

comment Rational + irrational = always irrational?
I think they were just pointing out that you can't use a fact without proving it. With what you said how does somebody know if the fact that you're trying to use is if x + c (where c is rational) is irrational then x is irrational compared to using if x+c (where c is anything) is irrational then x is irrational. Clearly the second one is false (take c = -x). So you just need to be more clear in what you're using and only use facts that you've proven.

comment What's 4 times more likely than 80%?
Is there a specific reason for all the numbers to be in latex? It seems like the only thing it adds is rendering time...

comment Tricks to remember Fatou's lemma
I do the same except let fn be an indicator that x >= n so that lim inf of the integral is infinity.

comment using numbers 1 to 9 only once to equal 1 million
@gam3 multiplication by 10 you say? 1*10*10*10*10*10*10. And do we have to use each digit 1 time?

Also there is no guarantee that you'll end up with a single loop.
