4 thoughts on “Why do we reverse/flip the inequality sign?

  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 $latex x > 5/3$.

  2. i’m in 7th grade ‘n doing Algebra 1 and i don’t understand this wording…. could someone explain dis 2 meh?
