Functions that have parentheses (sin(, log(, etc., functions that take
an argument to the right, functions that require a closing parenthesis
after the argument)

10 Addition (+), subtraction (−)
11 and (logical operator)
12 or, xor, xnor (logical operators)
Note: When squaring a negative value (such as -2), the value being
squared must be enclosed in parentheses (2). Since [
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 䌮 can be input in natural textbook format by using templates that
appear when certain keys are pressed.
Example: ͵
ͳ
ʹ
ͷ
͵
ʹ
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.
() 532
Tip: While the input cursor is located within the input area of a template
(mixed fractions), 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.
