The mental challenges using matchsticks have been seen a lot on the internet, as these utensils are known to everyone around the world. world and tend to attract attention. By fiddling with a toothpick, for example, it is usually possible to create a new figure, number or object in a “puzzle”, but this simple level math test is different! Here you must create a Roman equation without moving any of them.

roman equation
The Roman numeral system was developed in Ancient Rome and uses seven letters of the Latin alphabet that are combined to form different numbers. The seven letters are: I, V, X, L, C, D and M.

How can I solve the challenge if I can't move the matchsticks?
This is an important tip: you don't need to move the sticks, but you are free to move the image. That means you can flip the image horizontally, vertically or you can mirror it. You can make combinations of inverting and mirroring, for example. There are several possibilities, but only one of them results in a Roman equation.
Explore the possibilities and, if you like, do more tests related to Roman numerals to warm up. Although it is not the numbering system used in the West, it is used by many peoples and is present in numerous moments, such as the division of book chapters, in classic documents and various others. In a globalized world, it is increasingly important to have contact with the various numbering systems.
Result

This challenge is of low complexity. You already got it?
