E-8
5th
Negative sign (–)
Note: When squaring a negative value (such as –2), the value
being squared must be enclosed in parentheses (
(- 2 )w
=). Since x 2 has a higher priority than the negative sign,
inputting
- 2 w= would result in the squaring of 2 and then
appending a negative sign to the result. Always keep the priority
sequence in mind, and enclose negative values in parentheses
when required.
6th STAT Mode estimated values ( m, n, m

7th Multiplication where the multiplication sign is omitted
8th Permutation ( n P r ), combination ( n C r )
9th Multiplication (
×), division ( ÷) , remainder calculations (÷R)
10th Addition, subtraction (+, –)
Inputting with Natural Display
Selecting Natural Display makes it possible to input and display fractions and
certain functions (log,
x 2 , x 3 , x ^, ), #, ", x −1 , 10
^, e ^, Abs) just as they
are written in your textbook.

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
argument of a function. After you have input 7
6
, for example, you can make
it the argument of
', resulting in 7
