    Ok, so it's a triangle and you must use the numbers 1-9 inclusive to make 21 on each side, so here's an example of the shape (edit shape wont work, anyway it's a triangle shape)....

    1
    2 3
    4 5
    6 7 8 9


    But each side of the triangle must add to 21, use number 1-9 only once.

    Have got it where sides are 21, 21 and then 22 :o

    PS - this is for a childs third class primary so embarrased I cannot get it :D:D
