Calculator 286
To calculate:
1. Enter all numbers and operators of your calculation. You can use the EE
button to enter a number in scientific notation. As soon as the number is
entered, Calculator converts it to standard notation.
2. Click on the
=
button or press
ENTER
. The result appears in the Readout
bar. Press on
ENTER
only once. If you press twice and a previous
operation is stored in memory, the Calculator will apply this operation
to your result. Only those operations which apply one number to
another are stored and repeated in this way (such as +, -,
*
, and
).
Order of Operations
When you enter calculations that include more than one operation, the
Calculator performs the operations in the following sequence (order of
precedence):
1. Any numbers or expressions enclosed in parentheses
2. Multiplication and division
3. Addition and subtraction
If you enter arithmetic functions that have the same level of precedence
(such as 2 + 5 - 1), the operations are performed from left to right.
The final result of your calculation will always be the result of the above
sequence. For example, if you enter 3 + 4 X 6, the result is 27 (
42).
This result is based on 3 + 24 (the Calculator performed the multiplication
before it performed the addition).
Parentheses can be used to ensure that a particular operation is performed
first. For example, you could enter (3 + 4) X 6. The Calculator does the
parenthetical operation first: 3 + 4 = 7. After that, the Calculator performs
the multiplication: 7 X 6 = 42.
Using the mouse
In addition to using the mouse to click buttons and select menu items,
you can use it to edit the numbers in the Readout bar. Using the mouse,
you can select digits in the display, and move the insertion point. For
instance, if you entered the number 124, but meant to enter 14, you could
drag select the 2 and press
BACKSPACE
to delete it.
Using the keyboard as a keypad
You may find it easier to use the keyboard for entering numbers. If you
are using the numeric keypad, be sure that the
NUM LOCK
key is on (the
NUM indicator is highlighted). Pressing NUM LOCK toggles the indicator
between on and off as does clicking the NUM button with the mouse. The
NUM button is located in the lower left corner of the screen.
