Stick och brinn!
A perfect match?
As usual, this year's matchstick problem offered an unusual solution, in spite of being fairly straightforward. The object was to take two triangles and make four by moving as few matches as possible. Since a null solution was out of the question, many realized that one needs to move at least one matchstick - which also turned out to be the correct solution. One possible solution is shown above, but it is also possible to write the four using Roman numerals, IV. Correct answer: 1 (10 points)
