Inputting with Natural Display
Selecting Natural Display makes it possible to input and display fractions
and certain functions ( , , ,
,
,
, ,
, , Abs) just as
they are written in your textbook.
Example:
2 + √2
1 + √2

Important!
• Certain types of expressions can cause the height of an input expression to be greater
than one display line. The maximum allowable height of an input expression 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
and then use
and
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
argument of a function. After you have input
7

, for example, you can
make it the argument of √ , resulting in
√

Example:
To input 1 +
