When this happens, you can scroll back to the left by using B and C to move the cursor. • When Linear Display is selected, pressing D will cause the cursor to jump to the beginning of the calculation, while A will jump to the end. • When Natural Display is selected, pressing C while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing B while the cursor is at the beginning will cause it to jump to the end. • You can input up to 99 bytes for a calculation. Each numeral, symbol, or function normally uses one byte. Some functions require three to 13 bytes. • The cursor will change shape to I when there are 10 bytes or less of allowed input remaining. If this happens, end calculation input and then press ... Calculation Priority Sequence The priority sequence of input calculations is evaluated in accordance with the rules below. When the priority of two expressions is the same, the calculation is performed from left to right. 1st 2nd 3rd 4th Parenthetical expressions Functions that require an argument to the right and a closing parenthesis “)” following the argument. , x–1 g Functions that come after the input value (x2, x3, x!,°’”,°, r, , %), powers (x..), roots (..) Fractions E-7 5th Negative sign (–) Note: When squaring a negative value (such as –2), the value being squared must be enclosed in parentheses (.... 2 ....; ..). Since x2 has a higher priority than the negative sign, inputting .. 2 .. would result in the squaring of 2 and then appending a negative sign to the result. Always keep the priority sequence in mind, and enclose negative values in parentheses when required. 6th STAT Mode estimated values (.., .., ..1, ..2) 7th Multiplication where the multiplication sign is omitted 8th Permutation (nPr), combination (nCr) 9th Multiplication, division (..,.) 10th Addition, subtraction (+, –) Inputting with Natural Display Selecting Natural Display makes it possible to input and display fractions and certain functions (log, x2, x3, x.., .., .., .., x.1,10.., e.., Abs) just as they are written in your textbook. 2 + '2 1 + '2 .. 2 .. 2....1 .. 2 ................ Important: • Certain types of expressions can cause the height of a calculation formula to be greater than one display line. The maximum allowable height of a calculation formula is two display screens (31 dots .. 2). Further input will become impossible if the height of the calculation you are inputting exceeds the allowable limit. • Nesting of functions and parentheses is allowed. Further input will become impossible if you nest too many functions and/or parentheses. If this happens, divide the calculation into multiple parts and calculate each part separately. Note: When you press and obtain a calculation result using Natural Display, part of the expression you input may be cut off. If you need to view the entire input expression again, press and then use B and C to scroll the input expression. Using Values and Expressions as Arguments (Natural Display only) A value or an expression that you have already input can be used as the argument of a function. After you have input 67 , for example, you can make '7 it the argument of .., resulting in . 6 Toinput1+ 7 andthenchangeitto1+ 7 .. ' 66 17 .. 6 ............(INS) ................ ................ E-8 .......................... As shown above, the value or expression to the right of the cursor after ....(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.) This capability can be used with the following functions: , , ....(..), ....(..), ....(..), .., .., ....(..), ... Overwrite Input Mode (Linear Display only) You can select either insert or overwrite as the input mode, but only while Linear Display is selected. In the overwrite mode, text you input replaces the text at the current cursor location. You can toggle between the insert and overwrite modes by performing the operations: ....(INS). The cursor appears as “I” in the insert mode and as “ ” in the overwrite mode. Note: Natural Display always uses the insert mode, so changing display format from Linear Display to Natural Display will automatically switch to the insert mode. Correcting and Clearing an Expression To delete a single character or function: Move the cursor so it is directly to the right of the character or function you want to delete, and then press ... In the overwrite mode, move the cursor so it is directly under the character or function you want to delete, and then press ... To insert a character or function into a calculation: Use B and C to move the cursor to the location where you want to insert the character or function and then input it. Be sure always to use the insert mode if Linear Display is selected. To clear all of the calculation you are inputting: Pres...
