Negative sign (–)

 

Note: When squaring a negative value (such as –2), the value

 

being squared must be enclosed in parentheses ((-2 )w

5th

=). Since x2 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, m1, m2)

 

 

7th

Multiplication where the multiplication sign is omitted

 

 

8th

Permutation (nPr), combination (nCr)

 

 

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, x2, x3, x^, ), #, ", x−1, 10^, e^, Abs) just as they are written in your textbook.

Math

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 67 , for example, you can make it the argument of ', resulting in'67 .

To input 1 + 67 and then change it to 1 +'67 B
