It is true.
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.)

False
FALSE
It is true.
False.
It's false because there are other numbers ending 0 being multiples of 5.
They only end in zero, the simplist of people could have figured this out, but I will explain anyway. It is because every time 10 gets multiplied, id is moved on to the next set of 10 example: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
