Important: If you execute a calculation that includes both division and multiplication operations in which a multiplication sign has been omitted, parentheses will be inserted automatically as shown in the examples below.
• When a multiplication sign is omitted immediately before an open parenthesis or after a closed parenthesis.
6 ÷ 2 (1 + 2) é 6 ÷ (2 (1 + 2)) 6 ÷ A (1 + 2) é 6 ÷ (A (1 + 2)) 1 ÷ (2 + 3) sin(30) é 1 ÷ ((2 + 3) sin(30))
• When a multiplication sign is omitted immediately before a variable, a constant, etc.
6 ÷ 2π é 6 ÷ (2π)
2 ÷ 2'2 é 2 ÷ (2'2)
4π ÷ 2π é 4π ÷ (2π)
• When inputting a function that uses commas (such as Pol, Rec, and RanInt#), be sure to input the closed parentheses required by the expression. If you do not input closed parentheses, parentheses may not be inserted automatically as described above.

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. • When Linear Display is selected, pressing f will cause the cursor to jump to the beginning of the calculation, while c will jump to the end. • When Natural Display is selected, 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.

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

As shown above, the value or expression to the right of the cursor after 1Y(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.) This capability can be used with the following functions: ', 1'((), 16("), 1l($), 1i(%), !, 6, 1!(#), D.
Overwrite Input Mode (Linear Display only)
You can select either insert or overwrite as the input mode, but only while Linear Display is selected. In the overwrite mode, text you input replaces the text at the current cursor location. You can toggle between the insert and overwrite modes by performing the operations: 1Y(INS). The cursor appears as “
Note: Natural Display always uses the insert mode, so changing display format from Linear Display to Natural Display will automatically switch to the insert mode.

Correcting and Clearing an Expression
To delete a single character or function: Move the cursor so it is directly to
the right of the character or function you want to delete, and then press Y. In the overwrite mode, move the cursor so it is directly under the character or function you want to delete, and then press Y. To insert a character or function into a calculation: Use d and e to move the cursor to the location where you want to insert the character or
