... . But how thickly distributed are the primes? That is, if we pick a random number in {1…n}, what’s the probability of getting a prime? We’ll see a better characterization of p(n) shortly. ...

... (Notice how just adding 1 to 10! reduced the number of prime factors.) For two integers m & n with n>m we say the remainder of n divided by m is r if n = qm + r, for integers q &r with 0

... Average speed = total distance/total time = 2d/total time Total time = d/10 + d/15 = d /6 Avg. speed = 2d / d/6 = 12. 4. What is the largest possible value for the sum of two fractions such that each of the four 1-digit prime numbers occurs as one of the numerators or denominators? ...

... 8. [8] What is the largest positive integer that cannot be expressed as a sum of non-negative integer multiples of 13, 17 and 23? Solution There are numerous approaches to this problem, and no approach that attempts to find the last obtained remainder modulo any of the three numbers in sums of them ...
