e while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing d while the cursor is at the beginning will cause it to jump to the end. • You can input up to 99 bytes for a calculation. Each numeral, symbol, or function normally uses one byte. Some functions require three to 13 bytes. • The cursor will change shape to kwhen there are 10 bytes or less of allowed input remaining. If this happens, end calculation input and then press =.

Calculation Priority Sequence

The priority sequence of input calculations is evaluated in accordance with the rules below. When the priority of two expressions is the same, the calculation is performed from left to right.

1st

Parenthetical expressions

 

 

2nd

Functions that require an argument to the right and a closing

parenthesis “)” following the argument.

 

 

 

3rd

Functions that come after the input value (x2, x3, x–1, x!, °’ ”, °, r, g,

%, 't), powers (x^), roots (")

 

 

 

4th

Fractions

 

 

 

Negative sign (–), base-nsymbols (d, h, b, o)

 

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

Metric conversion commands (cm'in, etc.),

STAT Mode estimated values (m, n, m1, m2)

 

 

 

7th

Multiplication where the multiplication sign is omitted

 

 

8th

Permutation (nPr), combination (nCr), complex number polar

coordinate symbol (∠)

 

 

 

9th

Dot product (·)

 

 

10th

Multiplication (⋅), division (÷), remainder calculations (÷R)

 

 

11th

Addition, subtraction (+, –)

 

 

12th

Logical AND (and)

 

 

13th

Logical OR, XOR, XNOR (or, xor, xnor)

 

 

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^, ∫ , d/dx, Σ, Π, Abs) just as they are written in your textbook.
