  • what the heck did they teach us right to left in school.....FML.

  • thnx alot, jimmyclassic! it really helps,but sometimes it doesn't work perfectly, e.g. try this:

    6783+4917, using ur method it's 11600, but 11700 is the right result. Any ideas why?

  • @henryhan1901 you have to remember to add your remainders over 10 to the previous number

  • some1 plz tell me the method largest than this if exist..........

  • You must be joking...Ups. Sorry, I just realised that many people had no math at primary school.

  • Comment removed

  • OMFG THISIS AMAZING!! THANKS JIMMY MAN YOU GOT A DONATION LINK AT ALL??

  • that what i calls a reallyy heulfuulll stuffff

  • really....very quick thanx..

  • wow thanks man

  • artofspeedmath(dot)com

    free speed math training program!

  • No. This is not the way to do it. Bad.

    I would just say:

    17 hundred, 130

    18 hundred 30, 18

    18 hundred 40, eight

    Figure it out yourself.

  • Nice post Jimmy. Thanks for sharing.

  • This is the reverse method that everyone else does surely? I do this but the other way round.

    And speed is deduced by practise and how intelligent the person is surely, not necessarily the method.

  • I like your method....but it has some shortcomings.

    For example, if you do:

    7532814+9467294

    then you realize you need to add 1 only towards the end...which in turn might take longer than conventional method.

    I can see you method working well for smaller and less 'tricky' additions.

  • never saw it that way 5/5 ;)

  • I hate math and i loved this one!:D

  • isn't it just easier to place them on top like this:

    _9731

    _7898 +

  • Finally....so many video's with these slow methods...where did they all come from..?

    Adding and multiplying works best when you place them on top of each other...and by the way.....these small numbers in this video...calculate them in your head is much quiker :)

  • dont understand it sorry bro

  • lol nvm mind iv just realized wt an idiot iv been it does work lol i kept writein 13 instead of 11

  • this may b stupid but y does 371+543=914 but if i do it ur way it equals 934? im confussed
