*1*2

*1 A multiplication symbol (⋅) can be omitted when it occurs immediately before an opening parenthesis, immediately before Rnd or RanInt# function that includes parentheses, immediately before the Ran# (random number) function, or immediately before independent memory (M) or π.

*2 The closing parenthesis immediately before the = operation can be omitted.

Note: • If the calculation becomes longer than the screen width during input, the screen will scroll automatically to the right and the ] indicator will appear on the display. When this happens, you can scroll back to the left by using d and e to move the cursor. • Pressing 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 k when 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 Function with parentheses: Rnd(, RanInt#(

3rd Functions that come after the input value (x2, x–1, °’ ”, %), powers (x^), square root ())

4th Fractions

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 Multiplication where the multiplication sign is omitted

7th Multiplication (⋅), division (÷), remainder calculations (÷R)

8th Addition, subtraction (+, –)

E-6
