Basic Features 7 1 Basic Features Welcome to the HP 20b Financial Calcula tor This manual is designed to familiarize you with the ma ny features of your new 20 b Financial C alculator. It includes m enu maps, example problems and solution s with key presses, screen shots, and example s of cash flow diagrams.
Basic Features 8 Two Line Displ ay There are two lines in the display screen as shown in Figure 1. Figure 1 Dis play Screen The top line of t he screen displays operation status, op erator symbols, annunciator s, and abbreviations of the registers, variables, and menu na mes.
Basic Features 9 Table 1-1 Mode Menu Sett ings Setting (top line) Description FIX= 2 Display precision (number of digits displayed to the right of the decimal point). Default is 2 . Key in the number of digits you want and press I , or press = until the number of digits you want is displayed.
Basic Features 10 Table 1-1 Mode Menu Sett ings Setting (top line) Description English, Français, Deutch, o r Español Language s etting for the m essages displayed on the scr een. Default is English . Pressing I cycle s through these options. Actual or Cal.
Basic Features 11 Key Presses and the Se condary Function : Key To execute the function ass ociated with a key, pre ss and relea se the desire d key. M ost of the 20b's keys ha ve two f unctions: the primary func tion and t he second ary fun ction.
Basic Features 12 Figure 3 Annunciator Symbols in t he Screen Display The I Key The I key is used to input values for variables and execute menu items. The I key is also used in Reverse Polish Notation (RPN) mode to enter a number on the stack or duplicate it.
Basic Features 13 When an item f or wh ich the = key is valid d isplays, the small annunc iator (=) is d isplayed on t he to p line at the right of t he screen. Do not confuse this small annunciator ( =) with the larger annunciator (=) found to the right of a variab le.
Basic Features 14 For more information about storing and recalling numb ers, refer to the section titled, Storing and Recal ling Numbers in Chapter 2. The Cash Flow and Statistics menus share the same memory a nd are limited to a combined total of 50 memory slots.
Basic Features 15 In this manual, diagram s called Menu Maps are included at t he beg inning of each section to a ssist you wit h navigating through the m enus used for that sect ion. For an example of a menu map, see Figure 7. Figure 7 The Menu Map for the Break-even Menu There are four types of menu items: 1.
Mathematical Calculat ions 16 2 Mathematical Calculations Mathematical Fun ctions Mathematical functio ns are located: On keys, such as, +- */ , etc. On shifted, or s econdary functions, such a s, :p In the Math menu, :s Number Entry and D isplay Numbers are entered by pressi ng: Numbered keys, 0 - 9 The decimal p oint .
Mathematical Calculat ions 17 Chain Mode Calculations in C hain mode ar e interpreted in the order in which the y are entered. For examp le, enterin g the f ollowing numbers and operati ons as written from le ft to right 1+ 2*3= r eturns 9 . See Figure 2.
Mathematical Calculat ions 18 For example, key in 1+ 2 x 5 nPr2 2 in Algebr aic mode by pressi ng: 1+2 *5:b2 :m= . The re sult is 241. Note: the cal culator is limi ted to 12 pending oper ations. An operation is pending when it is waiting for the inpu t of a number or the result of an operation o f higher pr iority.
Mathematical Calculat ions 19 When an operation is performed on the stack, addition ( + ) for instance, the calculator "po ps" or move s the two numbers from the b ottom le vels (Lev els 1 and 2) ou t of t he stac k, perform s the oper ation, a nd "pu shes" th e results back into the stack.
Mathematical Calculat ions 20 Table 2-2 Last Number Keys Display Des cription +:d/ Adds 1. 23 and 56.123, then d ivides the sum b y the last number, 56.123. Returns results in the selected display format. For more co mplex problem s req uiring two or more operations, you do not need to enter parentheses to set operat ional priorit y.
Mathematical Calculat ions 21 Table 2-3 Simple Arithmetic Calc ulations in RPN M ode Keys Display Description RPN Stack * Finishes t he operation and displays the results. Pressing I or = when you are not entering a number duplicat es the number on Level 1.
Mathematical Calculat ions 22 Figure 6 The RPN Stack and the Roll Down Operation Pressing ) performs a swap . A swap operation ex changes the numbers o n Levels 1 a nd 2 of t he stack. The ) key ha s a small symbol on it as a reminder of the swap feature.
Mathematical Calculat ions 23 For example, to ca lculate 6 , press 6:n . The r esult of 2.45 is calculated immediately and d isplayed on the bottom line.
