Inputting and Editing Cell Data
k Inputting a Constant
An expression or value that you input without an equal (=) in front of it is called a “constant”,
because the value is not affected by anything outside of the cell where it is located.
If you input a math expression as a constant, the cell shows its result. A “Syntax ERROR” will
occur if an expression uses an incomplete or illegal syntax, or if its result is a list or matrix.
The following table shows various types of constants and the results they display.

A character string like AX is treated as a series
of variables (page 2-2-1).
To have a character string treated as text, start it
with a quote mark (").
