i am me because of you

Are you able to work out problems like this in your head?
Give an example of how far you can go up to…. be honest.

Example: I am learning how to calculate 317 + 58 in my head. The answer is……

    Wow!!! This method really helps me. I totally understand, but i dong get it when you round two numbers. For example 657=58 i don’t round 657, i round 58 to 60. But i understand.

    Really good answers to the compensation strategy

  3. I am able to work out problems like in my head but I’m not sure of some other ones. I can go up until 805+89! Maybe but I’m not really sure I’ll try work it out here at home!!!!

  4. By the way ruby why were you smiling at the background.

  5. example:714+522=1236

    I like mental maths I think people wanted to know why I did smile at the camera because I was impressed at saloni when she was talking anyways good job saloni…Mr Chad did u put the video in YouTube

    I am really good at compensation strategy and mental thinking. I can go up to 4 by 4 digit, sometimes.

    For example: I can try sums like 2,349+4,276.
    I do it like this:2,349+4,276=2,350(+1)+4,276=6,626(-1)=6,525
    That one was a bit difficult, but I think I’m right.

      I am now really quick at mental maths, because of me practicing and the compensation strategy that Mr Chad taught us. I really like doing sums in my head instead of always writing it in your book. Thank you, Mr Chad for teaching and extending our learning in mental maths:)!

  10. I think i can do sums like that in my head and the farthest number is 999+100

  11. Saloni Patel said:

    This method has really taught me how to solve problems mentally in maths and I am looking forward to doing sums like 5904-286. Apart from that I really love to see that I am on YOUTUBE!!!!

    • Rahul Doshi said:

      Me, too. I am really burning to start subtraction. It didn’t look so complicated when Mr Chad showed us. I want to learn! Don’t touch me! I’m burning!

  12. good answer compensation strategy rooks!!!!!!!…


  14. ……………………………!!!!!!!!!!!!!!!!!!!

  15. I MEAN YES

  16. Sarah Cochu said:

    the highest I can go i think is 3 digit by 3 digit for example

  17. I really like this method it changed me on maths i can i’ven solve problems easly on my head this is my moment to learn more sums then anyone .

  18. I enjoyed the video because it shows me many things

      compentestion starety is kind of hard but am getting it but the hard part is how to do the mental math in your head

  19. Mehwish Punjani said:

    i ment talal

  20. its kind of a game actually because as i do the maths i also test my timing. i think this method helps one to think critically and more deeply and keenly. for those who hate maths i hope this will be an eye opener for them because maths is also about fun!

  21. Sarah Rishad said:

    No no no I don’t anyone to see me in YouTube I am going to ask sir to take a video of me doing a difficult sum

  22. samia juma said:

    it is not completely easy but I am confident in compensation strategy. I just need to work on doing it in my head

  23. samia juma said:

    I would reaaallllyyyy llloooovvveee to be on youtube

  24. This is a test.

  25. it is great that saloni was able to say explanation in front of all briskly properly.

  26. Tiana Vora said:

    WOW Saloni !!! You are really GR8 in computation strategy. I wish I was like you.

  27. samia juma said:

    sometimes I can do 4 digit by 3 digit for example 1432+346=1778

  28. Hisham Ladha said:

    One of the first questions I gave myself was 999+999=1000(+1)+999=1999(-1)=1998.

  29. I am getting better at it but i can only do 2 digit by 2 digit.like.

  30. Jai Mr chad allowed us

  31. wooooooooooooooooooooohoooooooooooooooooo

  32. i am liking it.

  33. what are you liking

  34. I mean what are you liking taia

  35. sir I guess the compensation strategy is helping more but in subtraction if its 32 instead of you going to 40 you go to 30 but I don’t under stand how you add
