    Thank you for assisting me with teaching my most challenging classes. For some reason, the students are quiet and listen to you. I'm grateful for you. Then I get to walk around the room and help the students that need personal attention. I've never believed in playing videos for instruction inside the classroom. It has been a game changer. I stop the video after you write out the problem and give them time to think about how they would solve it. Again, thank you!

    Thank you so much. I'm in the advanced math class, and I've got a test on everything we learned last year, the first week of school. I had gotten my second vaccine when we were learning scientific notation and had to go home because I had a fever and couldn't make it through the day, therefore, I learned the method wrong. This just saved my grade on the upcoming test, so thank you ^^

  • @HawtLS
    @HawtLS 6 ปีที่แล้ว +10

    Overall, I loved the video. Very clear explanations. One quick comment; in the beginning you were talking about '9x' and '5x'. This might be a little confusing, since the 'x' isn't a variable in scientific notation; it's a multiplication sign. The operation isn't a part of the value, so it should just be 9-5, not 9x-5x.

    4:16 I think if you subtract 3.60 to 0.27 the answer would be 3.33 x 10^5. The creator did not subtract the zero and 7. He just simply bring down the 7 which is incorrect. Correct me if I'm wrong.
