👉 Solidness in mathematics refers to a property of a mathematical object that makes it more easily manipulated or understood than other objects. It is a characteristic that can be expressed quantitatively and can help in analyzing mathematical relationships and structures. For example, if you are working with a geometric shape, such as a square, and you want to understand the properties of this shape, you might say that it is solid because it has all four sides that are exactly the same length. This property helps mathematicians simplify
