(from Adam Wasserman) What is the degree of the highest exponent of K when you complete the operation: (K-A)(K-B)(K-C)...(K-Y)(K-Z) solution (from Ilya Sharapov) Prove that for any integer n the number [(2+sqrt(3)) n is odd. ( [x] is the integer part of x solution 2 kids, John and Jim, are running on an escalator (a moving stairway). John is running three times as fast as Jim, and by the time they are off the escalator, John has stepped on 75 stairs while Jim has stepped on 50 stairs. How many stairs does the escalator have? How is its speed related to the speed of the boys? Were they running with or against the escalator? solution Consider a sequence of n+1 integers a , a , ..., a n such that a k j . I.e., a is the number of zeros in the sequence, while a in the number of 20-ies in it. E.g., the sequence of length 4 satisfies the condition: these is only one zero there, so a , there are two ones, so a , there is one two, so a , and there are no threes, so a . Describe all such sequences. solution (from Bruno Haible Prove that for any positive integer n, the finite product
