My posts have dealt with the proof that multiplying two negative numbers always results in a positive number, which is the answer to the example the OP gave.
Your comments have nothing to do with either his question or my answer.
Your posts on the other hand involved multiplying by -1 a lot, without any explanation of what was going on. In addition, you multiplied two negative numbers (producing a positive number) in order to prove that two negative numbers produced a positive number. That kind of proof doesn't work in mathematics.
It would be like saying that all square roots are even, and then showing that the square root of 4 is 2 as proof.
Well, you caught me there.
