u Switching between Template Input and Line Input
Tap the L key. Each toggles the key color between white (L) and light blue ( ).
A white key indicates the template input mode, while a light blue key indicates the line input mode.
In the template input mode, you can perform template input using keys with
or
marked on their key tops,
such as N and !. Other keys input the same functions or commands as they do in the line mode.
Example 1: To use the template input mode to input
1. Tap the [Math1] tab and then enter the template input mode (white L key).
2. Perform the key operation below:
2+(N2!2c!2e+1
eem2E
Example 2: To use the line input mode to input the same expression as in Example 1
(
2+ (2 (2) / ( (2) + 1))^2
)
1. Tap the [Math1] tab and then enter the line input mode (light blue
key).
2. Perform the key operation below:
2+(d2!2)N
(!2)+1)ewE
Example 3: To use the template input mode to input
1. Tap the [Math2] tab and then enter the template input mode (white L key).
2. Perform the key operation below:
Oxe1f10exE
Example 4: To use the template input mode to input
1. Tap the [Math2] tab and then enter the template input mode (white L key).
2. Perform the key operation below:
7(1-xm2e)Qxeex
3. Tap the upper right input box of
and then press 1. Next, tap the lower
right input box of
and then press 0.
4. To execute the calculation, press E.
Tip: For information about the contents and input formats of the functions in Example 3 and Example 4, see “2-7 Using
the Action Menu” (page 61).
k Using Single-character Variables
As its name suggests, a single-character variable is a variable name that consists of a single character like
“a” or “x”. Input of single-character variable names is subject to different rules than input of a series of multiple
characters (like “abc”).
