  1. Can you learn multiplication because I’m in school and basically now that we are on let’s go help me get better

  2. Does Anybody know how to rounding numbers it its easy it just when you see there a number high than 5 (Example) 371+832 /800/400 so 800+400=1200 if im incorrect coment

  3. I think I might teach my little sister with this. She has trouble with math, and if I have a base like this to go off of, I can play it for her and when she's confused about something I can pause it and explain in-person. Thanks Khan Academy!

  4. so whatd you do to get the views? i see consistently 1-4000 views on your videos but these all of a sudden have a couple hundred thousand? hmm

  5. I LOVE this!  My son is getting ready to start 2nd grade.  I wanted to introduce him to multiplication before school because he is ready.  I have watched many videos from this teacher in Anatomy and Physiology and LOVED him.  Just like always, these concepts are displayed visually and clearly so that my son can understand.  Love the challenge at the end too.  I wouldn't change a thing!  Thank you so much! 

  6. My 3rd grade son would never be able to keep up with the speed of the narration delivered here. Keep in mind that the sole reason why a child would be watching this would be because he/she DOES NOT GET IT. Please speak more slowly. Thumbs down!
