The unit lets you use the result of one calculation as one of the arguments in the next calculation.
To do so, use the result of the previous calculation, which is currently stored in Answer Memory. Continuous calculations can also be used with Type A functions x 2 , x -1 , x! The Replay Function automatically stores the last calculation performed into replay memory.
You can recall the contents of the replay memory by pressing d or e. If you press e , the calculation appears with the cursor at the beginning.
Pressing d causes the calculation to appear with the cursor at the end. You can make changes in the calculation as you wish and then execute it again. Example To perform the following two calculations 4.
Note, however, that replay memory contents are cleared whenever you change to another mode or menu. Once you recall a calculation, you can use e and d to move the cursor around the calculation and make changes in it to create a new calculation. The large memory capacity of the unit makes it possible to store large amounts of data. You should note, however, that low battery power or incorrect replacement of the batteries that power the unit can cause the data stored in memory to be corrupted or even lost entirely.
Stored data can also be affected by strong electrostatic charge or strong impact. Since this calculator employs unused memory as a work area when performing its internal calculations, an error may occur when there is not enough memory available to perform calculations. To avoid such problems, it is a good idea to leave 1 or 2 kbytes of memory free unused at all times.
