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 A and then use d and e 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 76 , for example, you can make
| 7 | 7 |
| ||
To input 1 + |
| and then change it to 1 +' | B | ||
6 | |||||

As shown above, the value or expression to the right of the cursor after 1Y(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: ', &, 7, 17(F), 1&(8), a&(9), 16("), 1l($), 1i(%), !, 6, 1!(#), 1w(Abs).
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: 1Y(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 Y. In the overwrite mode, move the cursor so it is directly under the character or function you want to delete, and then press Y.
