Rearrangements refer to the process of changing the order or structure of elements within a system. This can occur in various contexts, such as in mathematics, where numbers or variables are rearranged to solve equations, or in chemistry, where the arrangement of atoms in a molecule changes during a reaction. In everyday life, rearrangements can be seen when organizing physical spaces, like moving furniture in a room to create a more functional layout. They can also apply to data organization, such as sorting information in a spreadsheet to improve clarity and accessibility.
