Pressing e displays the cursor at the beginning of the calculation expression, while d displays it at the end. After you make the changes you want, press E to execute the calculation. Example: 4 x 3 + 2.5 = 14.5 4 x 3 - 7.1 = 4.9 E-29 d YIyIIyIIyI B00ES 4x3+2.51 Using Multi-statements in Calculations A multi-statement is a statement that is made up of multiple calculation expressions separated by special separator codes (: and A). The following examples show how the two separator codes differ from each other. {expression 1} : {expression 2} : .... : {expression n} Pressing E executes each expression in sequence, starting with {expression 1} and ending with the final expression in the series. After that, the result of the final expression appears on the display. Example: To perform the calculation 123 + 456, and then subtract its result from 1000 ^b E®®®0 1 — (Ans) E 123+456:1000-Ans I {expression 1} A {expression 2} A .... A {expression n} In this case, pressing E starts execution starting with {expression 1}. When execution reaches a A separator, execution pauses and the calculation result up to that point appears on the display. Pressing E again will resume execution from the expression below the A separator. Example: To display the result of the calculation 123 + 456, and then subtract it from 1000 0@0ffl0®0@®(A) E®®®0 1—(Ans) 123+456j 1000—Ansi E-30 e e Note • The IQd symbol turns on in the upper right corner of the display when execution of a multi-statement calculation has been paused by a A separator. • When performing a multi-statement calculation, Ans (Answer Memory) (page 32) is updated each time any of the statements that makes up a multi-statement produces a result. • You can mix “A” and separators within the same calculation. mi Your calculator includes the types of memory described below, which you can use for storage and recall of values. Memory Name Description Answer Memory Answer Memory contains the result of the last calculation you performed. Independent Memory Independent memory comes in handy when adding or subtracting multiple calculation results. Variables The letters A through Z can be assigned different values individually and used in calculations. Note that variable M is also used for storing independent memory values. Extra Variables You can create extra variables when you need storage for more values than provided by the 26 letters from A through Z. You can reserve up to 2372 extra variables, which are named Z[1], Z[2], etc. Formula Variables The following literal variables are used by the calculator’s built-in formulas or user formulas. • Lower-cast alphabetic characters: a through z • Greek characters: a through ra, A through n • Subscripted alphabetic and Greek characters: Ai, ao, rat, Ax, etc. For details about built-in formulas and formula variables, see “Built-in Formulas” (page 97). The types of memory described above are not cleared when you press the (O key, change to another mode, or turn off the calculator. E-31 Calculator Memory Operations 123+456, 1000-Ans 579 123+456, 1000-Ans 579 421 ■ Using Answer Memory (Ans) The result of any new calculation you perform on the calculator is stored automatically in Answer Memory (Ans). □ Automatic Insertion of Ans in Consecutive Calculations If you start a new calculation while the result of a previous calculation is still on the display, the calculator will insert Ans into the applicable location of the new calculation automatically. Example 1: To divide the result of 3 x 4 by 30 (Next) Pressing 0 inputs Ans automatically. Example 2: To determine the square root of the result of 3 + 4 25 5 Note • As in the above examples, the calculator automatically inserts Ans as the argument of any calculation operator or scientific function you input while a calculation result is on the display. • In the case of a function with a parenthetical argument (page 15), Ans automatically becomes the argument only in the case that you input the function alone and then press E. Note, however, that with natural display Ans may not become the argument automatically when using a function with a parenthetical argument. • Basically, Ans is inserted automatically only when the result of the previous calculation is still on the display, immediately after you executed the calculation that produced it. If you want to insert Ans after clearing the display by pressing (O, press d — (Ans). E-32 □ Inserting Ans into a Calculation Manually You can insert Ans into a calculation at the current cursor location by pressing id — (Ans). Example 1: To use the result of 123 + 456 in another calculation as shown below 123 + 456 = 579 789 - 579 = 210 “1=_ ^B id — (Ans) E Example 2: To determine the square root of 32 + 42 and then add ^B 3XfflS0E ! d — (Ans) 0ffl5E ■ Using Independent Memory Independent memory (M) is used mainly for calculating cumulative totals. □ Adding to Independent Memory While a val...
