User manual HP 17BII FINANCIAL BUSINESS CALCULATOR

[. . . ] Menus and messages show you options and guide you through problems. Built-in applications solve these business and financial tasks: Time Value of Money. For loans, savings, leasing, and amortization. Discounted cash flows for calculating net present value and internal rate of return. [. . . ] Pressing [, ], @[, and @] moves you through the list. 156 12: The Equation Solver Table 12-1. The SOLVE Menu Labels Menu Label Description Verifies the current equation and creates menu labels for it. This is necessary before doing any calculations. Accesses the ALPHA-Edit menu (page 31) so you can alter the current equation. The arrow keys move long equations across the display. Deletes the current equation or just its variables (that is, the space allotted in memory for the variables). Allows you to enter a new equation. While you're working with a specific equation in the Solver, the equation's own menu appears in the display. To retrieve the primary SOLVE menu, press e. Entering Equations To make an entry into the Solver list: 1. (To insert the new entry at the bottom of the list, press @]. ) 2. Use the ALPHA menu to type in characters (see page 30), and use the regular keyboard to type in digits and arithmetic operators (+, =, yx, etc. ). If you make a mistake, use < to backspace or C to start over. 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. You can alter the current equation using the ALPHA-Edit menu: 1. (See "Editing ALPHAbetic Text, " page 31. ) You can use < (backspace) and C (clear), as well. To insert letters, press and the appropriate letters. 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. The name precedes the equation, separated by a colon. 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.
