  • Man this is stupid it only aplies to certain numbers. Try 67 or what ever it doesnt add up.

  • Dear Chamillionaire993, I use just 2 EasyCal techniques to perform all my multiplication mentally.

    1) Base Multiplication

    2) Rainbow Multiplication

    If the given number is far from any Base then of course you need to use Rainbow Multiplication.

    See the Video Response I have attached below. Incidently I was given the number 67 to multiply mentally in a Live Seminar ( see the video below )

  • realy dont help with 45^2 or other smalls

  • Dear hammas74, to see how to square the numbers near Base 50, see the 2nd video on Glad2teach website ( link below the video above ).

    45^2

    45 is at a distance of (minus) 5 from Base 50.

    So subtract that from 25, you get 20 _ _ ( you get first two Answer digits )

    Now for the last 2 Answer digits, simple write the square of that distance (minus) 5

    That is 25

    So the final Answer of 45^2 = 2025 ( Ins't that easy !! )
