HP 15c Collector's Edition User Manual

The HP 15c: A Problem Solver 13
The display format used in this handbook is • 4 (the decimal point is
“fixed” to show four decimal places) unless otherwise mentioned. If your
calculator does not show four decimal places, you may want to press ´
• 4 to match the displays in the examples.
Manual Solutions
Run through the following two-number calculations. It is not necessary
to clear the calculator between problems. If you enter a digit incorrectly,
press − to undo the mistake, then key in the correct number.
To Compute: Keystrokes Display
9 − 6 = 3
9 v 6 -
3.0000
9 × 6 = 54
9 v 6 *
54.0000
9 ÷ 6 = 1.5
9 v 6 ÷
1.5000
9
6
= 531,441
9 v 6 y
531,441.0000
Notice that in the four examples:
 Both numbers are in the calculator before you press the function
key.
 v is used only to separate two numbers that are keyed in one
after the other.
 Pressing a numeric function key, in this case -, *, ÷, or y,
executes the function immediately and displays the result.
To see the close relationship between manual and programmed problem
solving, let’s first calculate the solution to a problem manually, that is,
from the keyboard. Then we’ll use a program to calculate the solution to
the same problem with different data.
