As shown in the above Example, you can input simple arithmetic calculations using either the keypad keys or the soft keyboard. Input using the soft keyboard is required to input higher level calculation expressions, functions, variables, etc. See Chapter 2 for more information about inputting expressions.

Tip: In some cases, the input expression and output expression (result) may not fit in the display area. If this happens, tap the left or right arrows that appear on the display to scroll the expression screen and view the part that does not fit.

You can also change the display orientation to horizontal (landscape) for easier-to-read display of long input formulas and calculation results. See “Changing the Display Orientation (Main Application Only)” (page 14).

kEditing InputuTo delete a single character

Move the cursor so it is directly to the right of the character you want to delete, and then press K. Each press of Kdeletes one character to the left of the cursor.

Example: To change the expression 369 × × 2 to 369 × 21. c369**22. dK

After you make all of the changes you want, press Eto calculate the result. To add more characters to the calculation, press e to move the cursor to the end of the calculation, and input what you want.

Tip: You can move the cursor without using the cursor key by tapping at the destination with the stylus. This causes the cursor to jump to the location where you tap.

uTo insert new input into the middle of an existing calculation expression

Use d or e to move the cursor to the location where you want to insert new input, and then input what you want.

Example: To change 302 to sin(30)2 (For input, use the keypad and the [Math1] soft keyboard set.)

1. c30x2. dddds3. ee)uTo replace a range of input with new input

After you drag the stylus across the range of input that you want to replace, enter the new input. Example: To change “1234567” to “10567”

1. c12345672. Drag the stylus across “234” to select it.
