  • Game No. 1

    Study the circles below.

    Work out what number should replace the question

    mark.

    Hit

    4 * 5 + 3* 6 = 38

    8 * 4 + 3 * 5 = 47

  • GameNo. 2

     Draw a square made up of dots like this one on

    your piece of paper

     Now, without lifting the pencil from the page,

    draw no more than four straight lines which will

    cross through all nine dots

  • Hint

    One line can go out of the paper

  • Solution

    • Lessons Learned

    • Do not discard small details

    • Ask questions

    Vision Ahead of its Time

    The most profound

    technologies are those

    that disappear. They

    weave themselves into

    the fabric of everyday life

    until they are

    indistinguishable from it.
