I assume you all understand Roman numerals. Before trying this puzzle, let me introduce the vinculum, which is a horizontal line added above the Roman numerals and multiplies them by 1000.
Why do I mention this? Because it helps solve the following puzzle.
Here we have 6 matchsticks. Can you use them to express 100?
P.S. Finally, we have reached the 100th matchstick puzzles. Thanks for your visit! If you have time, please leave a comment to me (a simple greeting is enough :D). Your support is highly appreciated.
