[. . . ] To do a calculation using a Solver menu: 158 12: The Equation Solver 1. Store values in all but one of the variables (for example, 2000 , etc. ). To start the calculation, press the menu key for the variable you want to calculate. In most cases, this is all you need to know about how the Solver works. If, during the calculation, the display temporarily shows two lines of changing numbers, such as then the Solver is searching for a result for the variable A. Read the section, "How the Solver Works, " starting on page 179. The Return on Equity of a business can be defined as: ROE Operating income - Interest - Taxes Common equity Find the ROE of a small firm with $2, 000 in assets. The assets were financed using $500 of common equity and $1, 500 of debt. Operating incomeassets × percentage earnings on assets Interestdebt × percentage interest paid on debt Common equityamount of common equity used for financing The Solver equation would be: 12: The Equation Solver 159 Keys: Display: Description: Restores MAIN menu. Entering the equation. @A ROE = ( ASSET * % ERN - DEBT * % INT - TAX ) / EQTY I Stores the equation. Verifies the equation and displays the menu labels for ROE, ASSET, %ERN, DEBT, %INT, and (press ) TAX and EQTY. 2000 10 Stores the values for the assets, the percentage earnings on assets, the amount of debt, the percentage interest paid on the debt, the taxes paid, and the common equity. The return on equity is 16%. 1500 8 0 500 160 12: The Equation Solver Editing an Equation (EDIT) If you have an , the cursor stops over the first character that the Solver could not logically interpret. (See "Editing ALPHAbetic Text, " page 31. ) You can use < (backspace) and C (clear), as well. Press e I to replace the previous version with the edited version. Editing an equation clears its variables. To abort an editing operation without saving any of the changes, press e. Naming an Equation Naming equations helps you identify them later. If you don't name an equation initially, you can name it later using . Type the name just as you type the rest of the equation. The calculator knows that whatever comes before the colon is not part of the equation. The name is for your visual aid only; the calculator cannot recognize it. Names can be any length and contain any character except x ÷ ( ) ^ space 12: The Equation Solver 161 Finding an Equation in the Solver List To display an entry in the Solver list, display the SOLVE menu and move through the list using the [ and ] keys. @[ moves to and @] moves to . Shared Variables If two or more equations contain the same variable, that variable is shared among those equations. For example, suppose your Solver list of equations includes these two equations labeled RUG, which figures the cost of a carpet, and TOTAL, which figures the total cost of buying a carpet and installing it: COST is a shared variable. You can calculate a value for COST using the RUG equation, then switch to the TOTAL equation and calculate CHARGE after entering HOURS.
