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 +, –, #, or $.

•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 ## 2 = would produce a result of 8.

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 (+, –, #, $), simply tap the correct 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.
