Note: When squaring a negative value (such as -2), the value being
squared must be enclosed in parentheses (2). Since x
2
has
a higher priority than the negative sign, inputting 2 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.
Inputting an Expression Using Natural Textbook
Format (MathI/MathO or MathI/DecimalO Only)
Formulas and expressions that include fractions and/or special functions
such as √ can be input in natural textbook format by using templates that
appear when certain keys are pressed.
Example: 3

+5

1. Press ().
• This inputs a mixed fraction template.
2. Input values into the integer, numerator, and denominator areas of the
template.

3. Do the same to input the remainder of the expression.
() 532
Tip: While the input cursor is located within the input area of a template
(mixed fractions, integration (∫), and sum (Σ)), pressing  jumps to the
position immediately following (to the right) of the template, while pressing
 jumps to the position immediate before (to the left of) it.
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  and then use  and  to scroll the input
expression.
