Constants: A constant is something whose value is fixed as soon as you
finalize its input. A constant can be either a numeric value, or a calculation
formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign
(=) in front of it.
Formula: A formula that starts out with an equal sign (=), such as =A1×2, is
executed as it is written.
Note: Inputting a constant into a cell will take up 10 bytes of memory,
regardless of the number of characters input. In the case of a formula, you
can input up to 49 bytes into each cell. Inputting a formula into a cell
requires 11 bytes in addition to the number of bytes for the actual formula
data.
To display the remaining input capacity: Press (Free Space).
To input a constant and/or formula into a cell
Ex 1: Into cells A1, A2, and A3, input constants 7×5, 7×6, and A2+7
respectively. And then, input the following formula into cell B1: =A1+7.
1. Move the cell cursor to cell A1.
2. Perform the key operation below.
7576(A)7
3. Move the cell cursor to cell B1, and then perform the key operation
below.
(=)(A)7
Note: You can specify whether a formula in the edit box should be
displayed as it is or as its calculation result value.
To edit existing cell data
1. Move the cell cursor to the cell whose contents you want to edit, and
then press (Edit Cell).
• Cell contents in the edit box will change from align right to align left. A
text cursor will appear in the edit box so you can edit its contents.
2. Use and to move the cursor around the contents of the cell, and
edit them as required.
3. To finalize and apply your edits, press .
To input a cell reference name using the Grab command
The Grab command can be used in place of manual reference name (such
as A1) input using a key operation to select and input a cell you want to
reference.
Ex 2: Continuing from Ex 1, input the following formula into cell B2: =A2+7.
1. Move the cell cursor to cell B2.
2. Perform the key operation below.
Cell Relative and Absolute References
There are two types of cell reference: relative and absolute.
Relative cell reference: The cell reference (A1) in a formula like =A1+7 is a
relative reference, which means that it changes depending on the cell
