E-7

Your calculator lets you input calculator formulas using the same format as 
they appear in your textbook (natural format). Fractions and special functions 
(

2

, 

^, ), 

−1

, 10

^) are also displayed in a natural format.

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, 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. 

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

6

'

 .

To input 1 +  7

6

 and then change it to 1 +

7

6

'

 

 1 

+ 7 ' 6

dddd1Y(INS)

!

As shown above, the value or expression to the right of the cursor after 
1Y(INS) are pressed becomes the argument of the function that is 
specified next. The range encompassed as the argument is everything up 
to the first open parenthesis to the right, if there is one, or everything up to 
the first function to the right (

'

2, 10

2

, etc.) 

This capability can be used with the following functions: 

', A, !, 6.
