1. Thank you for explaining this, I had problems with this but I get it now. I have one question, what happens if both a and b are negative? Would it still reverse the inequality sign? Thank you~

If you are referring to the proof, you would reverse it if $a$ and $b$ are negative, but multiplying them by a negative value that is $c$ will make them positive, so no need to reverse them. If you are however referring to inequalities like \$latex -3x < -5\$, then yes. The answer to that is \$latex x > 5/3\$.
