Omitting the Multiplication Sign
You can omit the multiplication sign ( ✕) in any of the following
cases.
• Before an open parentheses (
 ):2 ✕(5 + 4), etc.
• Before a general function:
2 ✕ sin (30), 2✕  (3), etc.
• Before a variable name, constant, or random number:
20 ✕A, 2✕ π , etc.
Final Closed Parentheses
You can omit one or more closed parentheses that come at
the end of a calculation immediately before pressing the

key. For details, see “Omitting a Final Closed Parentheses.”
Displaying a Long Expression
The display can show up to 15 characters at a time. Inputting
the 16th character causes the expression to shift to the left.
The
 indicator appears to the left of the expression,
indicating that it runs off the left side of the screen.
Input expression: 1111 + 2222 + 3333 + 444
Displayed Portion:
• When the  indicator is displayed, you can scroll left and
view the hidden characters by pressing the  key. This
will cause the  indicator to appear to the right of the
expression. Use the  key to scroll back.
Number of Input Characters (Bytes)
• You can input up to 99 bytes of data for a single
expression. Each key operation uses up one byte. A
function that requires two key operations to input (like

 (sin -1 )) also uses only one byte. Note that when you
input functions with Math format, each item you input uses
up more than one byte. For more information, see
“Inputting with Math Format.”
• Normally the input cursor appears as a straight vertical ( ❙ )
or horizontal ( _ ) flashing line on the display screen. When
there are 10 or fewer bytes of input remaining in the
current expression, the cursor changes to . If the 
cursor appears, terminate the expression at a convenient
point and calculate the result.
