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).
