Solver, like Goal Seek, uses an iterative method to perform its calculations. Using iteration means that Solver tries a solution, analyzes the results, tries another solution, and so on. However, this cyclic iteration isn’t just guesswork on Solver’s part. That would be silly. No, Solver examines how the results change with each new iteration and, through some sophisticated mathematical processes (which, thankfully, happen way in the background and can be ignored), can usually tell in what direction it should head for the solution.
