  • Thank you for many views of this video. I have been having a lot of fun doing these videos. If you don't like one, you may like another. But this is not a popularity contest. I am trying to show you something important for your life. Thank you all.

  • Okay your maths tips are amazing, and I need a lot of help with mental arithmetic. However I struggle to understand you. I find myself attempting to understand what you say - therefore missing your VERY useful tip. Perhaps illustrative teaching - for those who pick up info differently?

  • @Light4rmLove If you are watching the video on your cell phone, the information bubbles do not show as they do on the internet. However I will try to use more visual aids, as they are useful for more clarity. Thanks for your comments.

  • wow all of a sudden i feel smart thanks for the tips, u made it so easy. i use to keep a pen by the door so i can add the total amount with the delivery person's tip, thats how slow my math is....lol. ty now i just figure it out in my head. nice ty

  • It is very encouraging to read of your success with these methods and tips. The reason most people find math to be so difficult is the manner in which it is taught. Thank you for your words. I will continue to provide more clarity.

see all

  • I think you are the first subscription I have, and I am very happy about it because you have such valuable information to share. Thank you for your time.

  • Nicely done! It's good to see fellow mental math-ers! I was in UIL Mental Math in Elementary and ever since I do lots of number manipulation in my head, hundreds of times a day. I'll be watching more of your clips to see what I can pick up!

  • Amazing work!! You should start branching off into Algebra, calculus and trig. There are many who look for lessons on you tube. You'd be great!

  • If there are youtube heroes, I would nominate you - for your teaching and giving spirit. Helping kids understand they aren't dumb, they just don't think about the problem the right way. 'Here is another way to think'. I wish this was around when I was in school. I have invented a method myself but never thought to publish it.

  • Thanks for your understanding and support. We all can learn from one another.
