Q#1: For each pair of numbers‚ when the division algorithm is used to divide a by d‚ what are the quotient q and remainder r? (a) a = 88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is
