One step is taken up each time you press a number key or arithmetic operator key ( +, -, *, /). A ! or a (fx- 82MS/85MS/300MS/350MS only) key operation does not take up a step, so inputting !W( 3 '), for example, takes up only one step. • Whenever you input the 73rd step of any calculation, the cursor changes from “_” to “ k” to let you know memory is running low. Calculation Priority Sequence When the priority of two expressions is the same, the calculation is performed from left to right. 1st Function with parentheses: Pol( x , y ), Rec( r , ), RanInt#( a , b )* (*fx-82SX PLUS/220 PLUS only) 2nd Type A functions: With these functions, the value is entered and then the function key is pressed. ( x 3 , x 2 , x .1 , x !, ° ’ ”, m, m1 , m2 , n, °, r , g ) 3rd Powers and roots: ^( x y ), x ' 4th Fractions 5th Implied multiplication of . , e (natural logarithm base), memory name, or variable name: 2 . , 3 e , 5A, . A, etc. 6th Type B functions: With these functions, the function key is pressed and then the value is entered. ( ', 3 ', log, ln, e x , 10 x , sin, cos, tan, sin .1 , cos .1 , tan .1 , sinh, cosh, tanh, sinh .1 , cosh .1 , tanh .1 , (.)) 7th Implied multiplication of Type B functions: 2 '3, Alog2, etc. 8th Permutation ( n P r ), combination ( n C r ) 9th Multiplication, division ( . , .) 10th Addition, subtraction (+, –) Correcting and Clearing an Expression To delete a single character or function: 1 234_ > ddD > 12 4 To insert a character or function into a calculation: 123_ > d!D(INS) e > 1243 • The cursor changes from “_” to “ t”. To clear all of the calculation you are inputting: Press A. 13. Basic Calculations Fraction Calculations 2 + 1 = 1 3 2 6 1 2 $ 3 + 1 $ 2 = 1 {1 {6. 1 = 1 2 2 4 . 3 4 - 3 $ 1 $ 2 = 1 {2. Note: • Mixing fractions and decimal values in a calculation will cause the result to be displayed as a decimal value. • Fractions in calculation r esults are displayed after being reduced to their lowest terms. To switch a calculation result between improper fraction and m ixed fraction format: Press 1$( d/c ). To switch a calculation result between fraction and decimal f o rmat: Press $. Percent Calculations 150 . 20% = 30 150 * 20 1=(%) 30. Calculate what percentage of 880 is 660. (75%) 660 / 880 1=(%) 75. Increase 2500 by 15%. (2875) 2500 * 15 1=(%) + 2875. Discount 3500 by 25%. (2625) 3500 * 25 1=(%) - 2625. If 300 grams are added to a test sample originally weighing 500 grams, what is the percentage increase in weight? (160%) 300 +500 !=(%) 160. What is the percentage change when a value is increased from 40 to 46? (15%) 46 -40 !=(%) 15. Degree, Minute, Second (Sexagesimal) Calculations The following is the input format for a sexagesimal value: {degrees} $ {minutes} $ {seconds} $. k k k k k k Note: You must always input something for the degrees and minutes, even if they are zero. 2°20.30. + 39.30. = 3°00.00. 2 $ 20 $ 30 $+ 0 $ 39 $ 30 $= 3°0°0. Convert 2°15.18. to its decimal equivalent. 2 $ 15 $ 18 $= 2°15°18. (Converts sexagesimal to decimal.) $ 2.255 (Converts decimal to sexagesimal.) !$(<) 2°15°18. Multi-Statements (fx-82MS/85MS/300MS/350MS only) You can use the colon character (:) to connect two or more expressions and execute them in sequence from left to right when you press =. 3 + 3 : 3 . 3 3 + 3 Sr(:) 3 * 3 = 6. Disp = 9. Using Engineering Notation A simple key operation transforms a displayed value to engineering notation. Transform the value 1234 to engineering notation, shifting the decimal point to the right. 1234 = 1234. W 1.234.10 3 W 1234..100 Calculation History (Not included on the fx-82SX PLUS) In the COMP Mode, the calculator remembers up to approximately 150 bytes of data for the newest calculation. You can scroll through calculation history contents using f and c. 1 + 1 = 2 1 + 1 = 2. 2 + 2 = 4 2 + 2 = 4. 3 + 3 = 6 3 + 3 = 6. (Scrolls back.) f 4. (Scrolls back again.) f 2. Note: Calculation history data is all cleared whenever you press O, when you change to a different calculation mode, or whenever you initialize modes and settings. Replay (Not included on the fx-82SX PLUS) While a calculation result is on the display, you can press d or e to edit the expression you used for the previous calculation. 4 . 3 + 2.5 = 14.5 4 * 3 + 2.5 = 14.5 4 . 3 . 7.1 = 4.9 (Continuing) dYYYY- 7.1 = 4.9 Answer Memory (Ans) The last calculation result obtained is stored in Ans (answer) memory. Ans memory contents are updated whenever a new calculation result is displayed. To divide the result of 3 . 4 by 30 3 * 4 = 12. (Continuing) / 30 = 123 + 456 = 579 123 + 456 = 579. 789 – 579 = 210 (Continuing) 789 -G= 210. Variables (A, B, C, D, E, F, X, Y) (fx-82MS/85MS/300MS/350MS only) Your calculator has eight preset variables named A, B, C, D, E, F, X, and Y. To assign the result of 3 + 5 to variable A 3 + 5 1t(STO) y(A) 8. To multiply the contents of variable A by 10 (Continuing) Sy(A) * 10 = 8...
