  • an easier way to tell which way the less than or greater than sign points. < means the arrow points to the left and vise-versa.

  • @filipinoasain NO!!! That only works if the variable is on the left. For 3>x it will not work!!!

  • Why can't my math teacher teach it this simple?!?!?!

  • u Are awesome u helped me tostudy for my midterms :)

  • On "C," it is also EQUAL TO. Don't forget that, else you will get it wrong. :)

  • God bless you sir. You have helped me understand my Algebra homework when my nagging teacher at school couldn't adequately do so. Thank you.

  • @MarcWhitaker actually all u need 2 do is flip the x and 3 and make sure the variable is on the left

    EX: 3>x FLIP x<3

  • Youtube teacher FAIL lol

    @ 3:17 he makes a mistake and forgets that '2/3x' is greater than or EQUAL to '1'

    therefore he would have gotten this wrong and scored a 2/3 or 67%. Thats not even a C...

    but either way this guys teaching is awesome and totally helped me.

    I'm subscribing!

  • You're teaching is excellent! Thank you!

  • @filipinoasain yes I have done that before and i only got 12/26 right on the assignment it doesn't always work! careful!

  • My homework just became easier!! Thank you!!!!!!

  • he made a mistake at 4:20 otherwise great video
