1) (20 pts) Let n be an odd integer. Using direct proof, prove that n- 1 is divisible by 8. 2) (20 pts) Let A, B, and C be sets. Show that: (A - B) - C = (A -C) - (B-C). Hint: Start with the right side of the equation and use the Set Laws and Definitions to prove that this set is equivalent to the left side of the equation
