Prove or disprove (if false, give a counterexample): (a) If {n} and {yn} are both bounded above, then so is their sum (b) If {n} and {yn} are both bounded above, then so is their difference {In - Yn}. (c) If {n} and {yn} are sequences of nonnegative real numbers that are bounded above, then so is their product {xnyn}. (d) If {n} and {n} are sequences of positive real numbers that are In bounded above, then so is their quotient Yn
