    mkg335:

    Number of 1x1 squares = 24

    2x2 squares = 11

    3x3 squares = 4

    4x4 squares = 1

    ...for a grand total of 40

    Correct answer is 40.....

    Well the first correct answer I saw was  MBaggese ( he can stop feeling dizzy now....lol),  then along came Jsweetr (late coming through the system) and then Mkg335 ( I think edited his original number of 41....lol)     Balls will be sent  to all of those :).

    The Solution

    Roger, I did indeed edit my original answer (I had over-counted the 1x1's and undercounted the 2x2's).

    And Mike did indeed supply the correct answer first, so he's the one who deserves the balls.

    It's a very cool puzzle, thanks for posting it and thanks especially for being so generous.

    edit:  oops, I see jsweetcr did indeed post 40 first...nice going, sir!

    I seen that...lol   No Probs   balls sent.

    For something completly different ....      The other vids on the Solution page are not mine,  but I just watched the Finger Multiplication vid.  

    Not being a maths guru myself.....  It surprizes me sometimes how easy somebody can calculate with the most simplest of things.... without a calculator......lol

    I remember reading a post from a math guru, I think it was on a chess forum...someone had stated that 2 + 2 always equals 4.  The math guru replied, "No, not always.  For greater values of 2, 2 + 2 can equal 5."

    That's when I finally realized that math and I occupy different planets.

    2x2 squares = 11

    3x3 squares = 4

    4x4 squares = 1

    ...for a grand total of 40

    I see

    .5x.5 squares = 8 (breakdown of the center "1" squares)

    1x1 squares = 18 (4x4=16 making the big "4" square + 2 in the center)

    2x2 squares = 9 (3 rows, offset by 1 vertical, containing 3 each, offset by 1 horizontal)

    Would be nice to know how you see more, M. - would elevate the result to 48 56 ;)

    Agree to the nos. of 3x3 and 4x4 (combined 5).

    My result is 40 ;)
