 1h comment What are some alternatives to base number systems and their advantages? Yes, but that doesn¿t work as smoothly for all number in the range 366! and 365! So this method reduces length of large number while decreases number of symbols requfor small numbers, this is something a base system can't do 2h comment What are some alternatives to base number systems and their advantages? @moose I agree this particular system isn't a marvel, but for example: the number 6^1000-1 would take 999 digits in base 6. While it would take 365 in the one I proposed. 1d comment How to 'show your work' with game theoretic notation Could you give us some of your background? Are you a maths major? what year? Mar12 comment How many ways to make a bracelet with $n$ white balls and $m$ black balls? Oh, I see, but how can we count them then? Mar12 comment square numbers multiplied by non-square numbers Oh, of course, thanks for pointing it out. ;) Mar12 comment Application of Euler's theorem what is rulers theorem? Mar12 comment what is the probability that every man marry this year?? The number of ways to partition a set of size n into m parts is exactly S(n,m). Once a partition has been chosen(so the bundles of the domain have been asserted). All that is left to chose is which of these bundles will map to each of the elements of the codomain. We can do this in m! ways. So there are n!(S(n,m) surjective functions. However the probability a function will be surjective is (number of surjective functions)/(number of functions) and the number of functions is $n^m$ Mar12 comment How to prove $n^3 < 4^n$ using induction? Oh yes, thanks btw. Mar8 comment Standing Generalizations of the Collatz Conjecture? Nevermind, it turned out to be a summary Mar8 comment Standing Generalizations of the Collatz Conjecture? Yes, I found it in a chinese website, all I need to do is register. Mar8 comment Standing Generalizations of the Collatz Conjecture? No, I don't, but I might be able to find it online. Mar8 comment Standing Generalizations of the Collatz Conjecture? Yes, but only with other libraries from the business school I go to. They don't have that book, along with many others I've been meaning to read. Mar8 comment Standing Generalizations of the Collatz Conjecture? Yes, I do. But they mostly have business stuff. Mar8 comment Standing Generalizations of the Collatz Conjecture? Thanks, that book seems really interesting, unfortunately I don't have access to it. Mar7 comment what is the probability that every man marry this year?? you might also want to read up on the twelvefold way Mar6 comment Famous deaf mathematicians? But you can read the question Mar6 comment Famous deaf mathematicians? @dror what about arm wrestling? Mar6 comment Famous deaf mathematicians? @Dror what about deaf painters? Mar6 comment Famous deaf mathematicians? I'm not deaf so I can only speculate. I would imagine deaf people have a different inner structure for processing though. I usually produce words in my head, in the form of sound. This is how I develop thoughts, I speculate deaf people do it differently. Mar5 comment How to prove that the sum digits of repetend divide by the length of the repetend equal to 4.5? what is the repetend?
