How many digits are in the number 2^1000?
2^10 is three + one, I know that for sure: 1024 :)
2^100 - thirty + one
2^1000 is three hundred + one.
That's some weird math, though.
But I overdid it: there are 302 digits, but it won't be easy to prove. The fact that there are at least 301 is easy to prove. But to prove that there are exactly 302, you'll have to do a lot of work.

Oh, come on. It's an olympiad problem, you have to think.
Come on, relax, practice something else tomorrow :)

I met and even studied with them for two years afterwards. I was in the middle of the class :)

We had some too. Two. One went relatively far, but no further than a civil servant. So did the other. But no one became a trader.
Well, you don't need a lot of brains to be a trader. But to learn how to trade brilliantly, with outstanding results, you need brains.
