To perform constant calculations
1. On the calculator screen, input the first value of the operation, tap an
arithmetic operator key twice, and then input the second value of the
operation.
•
You can perform a constant calculation using +, –,
•
The first value you input (the one to the left of the arithmetic operator)
is the one that will be used as the constant.
•
Tapping an arithmetic operator key twice causes the indicator K to appear
on the display to indicate that a constant calculation is being performed.
2. Tap = to display the result of the operation.
•
Inputting 4
3. Tap = again to multiply the result by the constant.
•
Tapping = again with the example shown under step 2 would produce a
result of 32 (8 4).
•
Each subsequent tap of = multiplies the last result obtained by the
constant. Continuing with the above example, tapping = would produce
the following results: = 128 (32 4), = 512 (128 4), = 2048 (512 4),
and so on.
To correct entries during calculations
•
If you enter a wrong value, tap C to clear the value and then input the
correct one.
•
If you tap the wrong arithmetic key (+, –,
arithmetic key before inputting anything else.
About calculation errors
An error indicator appears on the display and further calculation becomes
impossible whenever an error occurs.
