... 1000000/5=200000 so there are 200000 numbers in that range divisible by 5, and 1000000/55=18181.8181.... so there are 18181 numbers in that range divisible by both 5 and 11. Thus there are 200000-18181 numbers in that range divisible by 5 but not 11. Answer: 181819 ...

... with q prime, there exists a prime number p such that p divides x and q divides p − 1. The last assertion easily follows from the first one. Indeed, let (x, y, n, q) be a solution of (1), not satisfying (H). Let p be a prime factor of x such that p does not divide y − 1. Regarding (1) modulo p, we h ...

... Say a sequence of n +1’s and n -1’s is a ballot sequence if every partial sum is non-negative. Call such a sequence TRIVIAL if n=0, PRIMITIVE if n>0 and all the partial sums are positive (except for the empty sum and the total sum), and COMPOSITE if n>0 and some partial sum is zero (i.e., the sequen ...
