What is the primary function of the Solver tool in Excel?

The primary function of the Solver tool in Excel is to set objectives and optimize values. Solver is an advanced feature used for optimization problems, where you define a cell to optimize (the objective cell), constraints that the solution must satisfy, and variable cells that Solver can adjust to achieve the desired outcome. This makes it an essential tool for tasks like maximizing profits, minimizing costs, or achieving specific targets while adhering to certain limitations. Other functions in Excel, such as analyzing data trends, creating charts, or formatting cells, serve different purposes and do not encompass the optimization capabilities that Solver provides.
