Inputting a Calculation Formula

Your calculator lets you input calculator formulas using the same format as

they appear in your textbook (natural format). Fractions and special functions

^, ),

−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.

Using Values and Expressions as Arguments

A value or an expression that you have already input can be used as the

argument of a function. After you have input

it the argument of ', resulting in

To input 1 + 7

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

This capability can be used with the following functions: ', A, !, 6.

and then change it to 1 +

! 63 =
