    I wish you'd covered the case when we're multiplying or dividing by x, as in that case whether the sign switches depends on whether x is a positive or negative number.

    As a parent this was very helpful. My child is in 7th grade at Del Valle ISD and her teacher doesn't explain this and she is lost and failing tests. Her teacher blames the students why they fail tests. Since are Elearning now I can show her this because this is what she is doing in Math now. She had a test yesterday with this and missed the questions and failed the test.

    • @EricBuffington
      @EricBuffington  4 роки тому +11

      I'm so sorry to hear she is struggling. Perhaps looking for a cyber charter school might be helpful for her. Agora Cyber Charter School is very good. At Agora they have certified teachers who walk students through the problems in live sessions and are amazing. Full disclosure, I'm one of the assistant principals at the Middle School in Agora so I am biased. :) Either way I'm so glad this video was able to help! Keep watching and have a wonderful day!
