10. A natural number n is called attainable if there exists non-negative integers a and b such that n - 5a + 8b. Otherwise, n is called unattainable. Construct an 9 x 6 matrix whose rows are indexed by the integers between 0 and 8 and whose columns are indexed by the integers between 0 and 5 whose (x, y)-th entry equals 5x + 8y for any 0 < r < 8 and (a) Mark down all the attainable numbers...

1. (Induction.) Consider the following program, called Ackbar(m,n). It takes in as input any two natural numbers m, n, and does the following: (i) If m-0, Ackbar(0, n) = n + 1. (ii) If n-0, Ackbar(rn,0) is equal to Ackbar(m-1, 1). iii) Otherwise, if n, m > 0, then Ackbar(m, n) can be found by calculating Ackbar(m - 1, Ackbar(m,n 1)) Here's a handful of calculations to illustrate this definition: Ackbar(1,0)-Ackbar(0,1) = 1 + 1-2 Ackbar (1, 1) Ackbar (0,...

7.6 Theorem. Let p be a prime. Then half the numbers not congruent to 0 modulo p in any complete nesidue system modulo p are quadratic residuess modulo p and half are quadratic non-residues modulo p. From clementary school days, we have known that the product of a pos- itive number and a positive number is positive, a positive times a negative is negative, and the product of two negative numbers is positive....
