  1. If the teacher doesn't say that you cannot repeat numbers, try this...

    Put 15 on all of the tips of the star and 0 on all of the vertices inside the star.


  2. so you mean this puzzle:

    First of all:

    never use numbers higher then 24, cause if you use all different numbers in rows of 4, the lowest 3 are 1, 2, 3. with 24 left to make 30

    apart from that I'm still guessing.

    haha, I hope you can't use the method of the person above me, that would be too easy :-P

  3. I found

    http://www.geocities.com/~harveyh/magics...

    about Magic Stars

    He shows two order 7 Magic Stars with sums of 30.

    I gather there are 70 others.

    A web search on Magic Stars should turn up more information.

    .

  4. whats guess and check?
