HP 300s+ Scientific manual Omitting the Multiplication Sign, Final Closed Parentheses

Page 16

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.
