Algorithms aren't new, they can be traced back millennia to Greek mathematicians such as Euclid, the 'father of geometry', who developed an algorithm that became the most efficient method for computing the greatest common divisor (GCD) of two numbers.
Here we have split each m uniquely into a part that has no common divisor with n and a part whose prime decomposition uses only the primes of n (note that there is no restriction on the prime powers used; e.g., [m.sub.2] = [n.sup.2] may appear in this decomposition for large enough x).
Chapters discuss the pigeonhole principle, the greatest common divisor, squares, digital sums, arithmetic and geometric progressions, complementary sequences, quadratic functions and equations, parametric solutions for real equations, the scalar project, equilateral triangles in the complex plane, recurrence relations, sequences given by implicit relations, and matrices associated to second order recurrences.
