´• 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

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

= 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.
