Probablybetteroffwithonewhichdoesn'thavethe'textbook'display(thefraction/surds).Theoldermodelhasthenormaldisplay Displaying a Long Expression The display can show up to 14 characters at a time. Inputting the 15th character causes the expression to shift to the left. At this time, the ] indicator appears to the left of the expression, indicating that it runs off the left side of the screen. Input expression: 1111 + 2222 + 3333 + 444 Math Displayed portion: Cursor • When the ] indicator is displayed, you can scroll left and view the hidden part by pressing the d key. Calculation Examples Using Independent Memory • If the “M” indicator is on the display, perform the procedure under “Clearing Independent Memory” before performing this example. Example: 23 + 9 = 32 23+9m 53 – 6 = 47 53-6m –)45 × 2 = 90 45*21m(M–) 99 ÷ 3 = 33 99/3m (Total) 22 tm(M) Clearing Independent Memory Press01t(STO)m. This clears independent memory and causes the “M” indicator to disappear from the display. The cursor key is marked with four arrows, indicating direction, as shown in the illustration nearby. In this User’s Guide, cursor key operation is indicated as f, c, d, and e.

Using Calculator Memory Memory Name Description Answer Memory Stores the last calculation result obtained. Independent Memory Calculation results can be added to or subtracted from independent memory. The “M” display indicator indicates data in independent memory. Variables Six variables named A, B, C, D, X, and Y can be used for storage of individual values. This section uses the COMP Mode (N1) to demonstrate how you can use memory.
