Ricci Decomposition is a way of taking a number, like 7, and breaking it up into two parts: 3 and 4, because 3+4=7. We can use this idea to break down numbers of more than one part and use that information to understand how the parts work together. For example, if you have a rectangle and you want to know the length of each side, you can measure the area of the rectangle, then use Ricci Decomposition to determine the size of the two sides.
