and the quotient is displayed. If a sum or a difference is formed before
or after entering the dividend in the calculator, this sum or difference
becomes the divisor when the (=) key is pressed, and with this the
division is automatically executed.
Example :
a : b = c
a :(b + c) = d
(a — b) : c = d
The calculated quotient, which is displayed, can be processed further
(see also calculation example 12).
4.5. Exponentiation
The base is entered by the (X) key. Each further press of the (Xn) key
increases the exponent by one. The power is automatically displayed (see
also calculation example 8).
4.6. Memories
All input values, results and constant factors can be stored in an
additive and subtractive way. Negative values are mathematically
processed correctly.
Values stored in the memories can be queried as often as desired by
pressing the (
▽
) key, whereby the value transferred in sequence is
retained in the memory. It is possible to transfer values from one memory
to another with the correct sign.
Example : (
▽
)
- Memory I, then
(+)
- Memory II
By pressing the (*) button (*I, *II, *III) the corresponding memory is
called up and deleted at the same time.
The value in the calculator can be processed further. Pressing the
(Delete Lö) key does not clear the memories.
Should the memory contents be checked during a calculation process.
without the last displayed value, eg. If the result or operand is lost,
proceed as follows:
The displayed value can be transferred to a calculation register by
pressing the (+) key. Thereafter, the memory can be queried, so that the
occupancy or content is known. By pressing the (=) - key the value in the
calculation register is displayed again..
4.7. Decimal point facility
The number of decimal places is set before the beginning of the
calculation by the knurled wheel to the left of the keyboard. When
setting the decimal point, the highest decimal place must be used. The
following decimal places are adjustable:
1-2-3-4-6-9-10-11-12—14
If the thumbwheel is set to "0", it is calculated without decimal places.
The setting "Z" is irrelevant for the type 220.
