This facilitates the simple construction of many different mathematical equations. Single-variable equations are among the easiest to construct when using this tool. Use the Equation Editor to insert an equation into any cell in your Excel worksheet.
Type a single-variable equation and select symbols from the "Equation" toolbar. Rahul and I are still chatting. I think the problem is solved but I am waiting for Rahul's final say so. I have a table in excel. I know the total value and I am trying to populate table so values tie out on coulmns to equal country sum and then on rows to sum to segment sum. Not sure if this makes sense but been struggling for hours with this!!!
Help please. Can you please ask the question in the chandoo. Thanks so much for your response to my inquiry, but I will appreciate a further detailed information in a vivid description.

Excel provides a simple explanation regarding when you should use each one. A better explanation requires some knowledge of statistics and regression. To adjust additional settings, just hit the Options button. You can tell Excel about integer optimality, set calculation time constraints useful for massive datasets , and adjust how the GRG and Evolutionary solving methods go about making their calculations.
Again, if you don't know what any of this means, don't worry about it. If you want to know more about which solving method to use, Engineer Excel has a good article that lays it out for you. If you want maximum accuracy, Evolutionary is probably a good way to go.
Just be aware that it will take a long time. Now that you're comfortable with the basics of solving for unknown variables in Excel, an entirely new world of spreadsheet calculation is open to you. Goal Seek can help you save time by making some calculations faster, and Solver adds a huge amount of power to Excel's calculating abilities. It's just a matter of getting comfortable with them. The more you use them, the more useful they'll become.

In the Subject to the Constraints box, add any constraints that you want to apply.
Note: You can only apply the int, bin, and dif relationships in constraints on decision variable cells. To interrupt the solution process, press ESC. Excel recalculates the sheet with the last values that are found for the adjustable cells. The report is created on a new sheet in your workbook. If Solver doesn't find a solution, the option to create a report is unavailable. To save your adjusting cell values as a scenario that you can display later, click Save Scenario in the Solver Results dialog box, and then type a name for the scenario in the Scenario Name box.
After you define a problem, in the Solver Parameters dialog box, click Options. Select the Show Iteration Results check box to see the values of each trial solution, and then click OK. Click Options , and then in the Options or Solver Options dialog box, choose one or more of the following options:. On the All Methods tab, under Solving Limits , in the Max Time Seconds box, type the number of seconds that you want to allow for the solution time.
Then, in the Iterations box, type the maximum number of iterations that you want to allow. Note: If the solution process reaches the maximum time or number of iterations before Solver finds a solution, Solver displays the Show Trial Solution dialog box. On the All Methods tab, in the Constraint Precision box, type the degree of precision that you want. The smaller the number, the higher the precision. On the GRG Nonlinear or Evolutionary tab, in the Convergence box, type the amount of relative change that you want to allow in the last five iterations before Solver stops with a solution.
The smaller the number, the less relative change is allowed. In the Solver Parameters dialog box, click Solve or Close. Tip: You can save the last selections in the Solver Parameters dialog box with a sheet by saving the workbook.
Each sheet in a workbook may have its own Solver selections, and all of them are saved. Use this method for linear programming problems. Portions are copyright by Optimal Methods, Inc.
