VPAM to show formulas as in textbooks (Visually Perfect Algebraic Method) .. Fraction key; Mixed number vs. improper fractions .. Recall and edit function .. Statistics mode including standard deviation and regression Content BASIC ARITHMETIC CALCULATIONS Mode 1 (Comp) Computation Making Corrections During Input Replay Function Order of Operations Display Format (FIX, SCI, Norm) Fraction Display Decimal-Fraction Conversion Angle Display Initial Defaults Percentage Calculations Degrees/Minutes/Seconds Memory Calculations Answer Memory Consecutive Calculations Independent Memory Variables Clearing Memory Powers/Square Roots/Cube Root, nth roots Probability Calculations/Random Number/Factorials Trigonometry Trigonometric/Inverse Trigonometric Functions Hyperbolic/ Inverse Hyperbolic Functions Convert Radians to Degrees Coordinate Conversion Logarithms/Natural Logarithms STATISTICAL CALCULATIONS Standard Deviation Mode 2 (SD) Standard Deviation Regression Mode 3 (Reg) Regression Basic Arithmetic Calculations Making Corrections During Input • Use the left and right arrows on the REPLAY function to move the cursor to the location you want to correct. • Press [DEL] to delete at the current cursor position • Press [SHIFT] [INS] to change the cursor to an insert cursor [ ]. Replay Function Every time you perform a calculation, the replay function stores the calculation formula and its result in replay memory. Pressing the up arrow displays the formula and result of the calculation you last performed. If you continue to press the up arrow, you will scroll sequentially through your last calculations (most recent to oldest). Notes: Replay memory capacity is 128 bytes. Pressing AC will not clear the replay memory. If you want to clear the replay memory, press the ON key or reset the modes/settings: Press [SHIFT] [CLR] [2] [=] or [SHIFT] [CLR] [3] [=] . Order of Operations The calculator uses “order of operations”. Examples: 2 + 3 x 4 = 14 You do not need parentheses around 3 x 4. (2 + 3) x 4 = 20 Use Replay and [SHIFT] [INS] to add parentheses. Blinking [ ] is the insert cursor. - 2 2 = - 4 (- 2) 2 = 4 Display Format To change the exponential display format, press the [MODE] key 3 times. Fixed number of decimal places: Press 1: FIX You will then be prompted for the number of decimal places (0 – 9). Scientific Notation: Press 2: SCI You will then be prompted for the number of significant digits (0 – 9). Normal Notation: Press 3: NORM You will then be prompted for NORM 1 or NORM 2. NORM 1 uses exponential notation for integers with more than 10 digits and decimal values with more than 2 decimal places. Ex/ 1 . 1000 = 1 x 10-3 NORM 2 uses exponential notation for integers with more than 10 digits and decimal values with more than 9 decimal places. Ex/ 1 . 1000 = .001 Fraction Display You can use the display set up screen to specify the display format when a fraction calculation result is greater than one. To set the fraction display, press the [MODE] key 4 times and press “1” for Display (DISP). Example Mixed Fraction: Press 1: a b/c Improper Fraction: Press 2: d/c 6173423=+ Decimal-Fraction Conversion Examples: Keystrokes Display Enter [2.75] [=] 2.75 Press [a b/c] 2 3 4 [SHIFT] [d/c] 11 4 Angle Display To set the angle unit at degrees, radians, or grads, press the [MODE] key 2 times. Degrees Press 1 Radians Press 2 Grads Press 3 Initial Defaults To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2] [=]. This will return the calculator to the following settings: Calculation mode COMP Angle unit Deg Exponential display format Norm 1 Fraction display format a b/c Decimal point character Dot Percentage Calculations Examples: Keystrokes Display To find percentage of a number. 12% of 15 [15] [x] [12] [SHIFT] [%] 1.8 To calculate percentage of one number to another. What percentage of 80 is 40? [40] [] [80] [SHIFT] [%] 50 . To add a percentage. 15% to 1000 [1000] [x] [15] [SHIFT] [%] [+] 1150 To discount a percentage. 85 by 10% [85] [x] [10] [SHIFT] [%] [ -] 76.5 % change, when a value is increased. From 30 to 36 [36] [–] [30] [SHIFT] [%] 20 Degrees/Minutes/Seconds You can perform calculations using degrees, minutes, and seconds, and convert between sexagesimal and decimal values. Examples: Keystrokes Display [2.5] [=] 2.5 Press [] 2° 30° 0 ,,,o [10] [] [15] [] [12] [] [x] [4] [=] 41° 0° 48° ,,,o,,,o,,,o Memory Calculations There are different types of memory available: Answer Memory, Consecutive Calculations, Independent Memory, and Variables. Answer Memory Whenever you press [=] after inputting values or an expression, the calculated result automatically updates the Answer Memory contents by storing the result. You can recall it by pressing [ANS]. Consecutive Calculations You can use the calculation result that is currently on display (and also stored in Answer Memory) as the first value of your next calculation. Independent Memory Independent Memory uses the memory area in variable M and i...
