... (18) and kfb = QAI, + I/, . Now If,, in binary, is a string of z ones, and if the division, Eq. (18), is carried out in binary we divide a string of a 1's into a ... obtain Eq. (5). Kow, from the next-to-last equation, a, is a linear combination, with integer coefficients, of a,-l and an-2. Again working backwards we see that a, is a linear ... generalized Theorem 13’ and in doing so he introduced an important function, +(n). Definition 9. If n is a positive integer, the number of positive integers prime to n and 5 n is called...
