| Negative sign | |
| Note: When squaring a negative value (such as | |
| being squared must be enclosed in parentheses (2 7 | |
5th | ). Since x2 has a higher priority than the negative sign, | |
inputting 2 7would 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. | |

Inputting with Natural Display
Selecting Natural Display makes it possible to input and display fractions and certain functions (log, x2, x3, x9, , , , x−1, 109, e9, 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 σ 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 B and C 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
7
argument of a function. After you have input 6 , for example, you can make
