Performing
Calculations
For each calculation,
enter both numbers
and operators. The numbers
are the
figures to be computed.
The operators
are symbols (such as + for addition).
An operation
is a combination
of an operator
and numbers (example:
100 +
200). A simple calculation
perfothas only one operation,
but a calculation
can
perform several operations.
For multiple operations,
you can tell Calculator
which operation
to do first or it will follow the Order of Operations
(see
below).
_ To calculate:
1. Enter all numbers
and operators
of your calculation. To enter a number
in
scientific notation, use the EE button. 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 ENTER only once. If you press twice and a previous operation
is stored in memory, the Calculator will apply this operation
to your resuk.
Only those operations
that apply one number to another are stored and
repeated
in this way (such as +, -,.,
and +).
Order of Operations
Calculator performs
muldl_!e calculations
in the following order:
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 (such as 2 + 5 - 1),
the operations
are performed
from left to right.
The final result of your calculation
will always be the resuk of the above
sequence.
For example,
if you enter 3 + 4 x 6, the result is 27 (not 42). This
result is based on 3 + 24 (the Calculator performed
the multiplication
before it
performed
the addition).
To ensure that an operation
is performed
first, use parentheses.
For example,
if you enter (3 + 4) × 6, Calculator does the parenthetical
operation
first (3 +
4 = 7), then the multiplication
(7. x 6 = 42).
