I never learn this type of math equations in school. Thank God for YouTube---I wish you YouTube was out back in the 90s and 80s..

I've always done this naturally without even being taught. I thought everyone did it like this...

I am learning but still slow though.
I am really bad at maths it's like I have a phobia or something when I watch those numbers my brain literally won't work.
I want to calculate numbers in my brain like very fast but i can't i had to use fingers to calculate, i hope i will be really fast in maths its my dream.

Here's another method I learned. 3+5+4+7+6+4+8+6+4+8+2+7.The method is to put a line under the number when you reach 10 or more. 3+5+4=12 Put a line under 4 and continue adding with the 2. So 2+7+6=15. Put a line under 6 and continue with 5. 5+4+8=17. Put a line under 8. 7+6=13. Put a line under 6. 3+4+8=15. 5+2+7=14.Put a line under 7. Write 4 in units place. Then count number of lines which will be 6. Write 6 in the tens place. This can be continued through into the tens, hundreds and thousands places. Actually there is no limit. .

It gets confusing with lots of numbers, how many compliments do you have, which ones are they, and whats left.

[ahmad.s]

Awesome, great videos for all ages.. thanks

[JoshLousk]

how is it mental math if youre having to color mark the complimenting numbers ( would have to be on paper)
? too confusing to keep up with unmarked in head in long strings of 10 or so, maybe im just not getting it

One thing that he leaves out is carrying numbers in your head...
