Question

Help with true or false for following 

T T T T T T T T T T F F F F F F F F F F If P, then Q is logically equivalent to If ~P, then ~Q. The statement ~P --> ~Q is the converse of P --> Q. The negation of ~P --> Q is ~P ^~Q. The statement P --> Q is equivalent to ~PV Q. To prove the statement: If ab = 0 then a = 0 or b = 0, you may assume ab = 0 and a 0 and then deduce that b = 0. If a = 4 (mod 8), then a² = 0 (mod 8). If a² = 1 (mod 8), then a = 1 (mod 8). For all integers n, 2 | (nª + n). The last digit of 6⁰⁰ is a six. The last two digits of 5¹33 are 33.
