A and B or C Does that even makes sense as a statement? I thought logical operators are binary. Obviously, the "or" links to C but what is on the other side? A or B? i mean 1+2-3=0 makes sense since (1+2)-3=3-3=0=1-1=1+(2-3) But [(A and B) or C]=(AorC)and(BorC) [ A and ( B or C) ]= (AandB)or(AandC) these are not the same.
