Method 2
In method 1 above, each argument is entered onto its own level of the
stack before the command is executed. Another way is to enter all the
elements onto the command line separatmg each with a space. You can
then either:
® press (ENTER) to place the arguments onto the stack and then execute
your command or
® execute your command with the arguments still on the command line.
Example: To
calculate -V531441
1. Enter 531441 (fc) 3
2. Press (EM).
3. Press
0(5f).
l:
531441 3
Step 2 can be omitted if you will not want to undo the command and see
the arguments. Pressing (R(DNDQ) without having first placed the arguments
on the stack deletes all record of the command: the result and the
arguments. On the other hand, if you place the arguments on the stack
before executing the command, pressing 0(D nd O) deletes the result but re­
displays the arguments.
Multi-command calculations
Because the result of a calculation is retained on the stack, you can easily
perform complex calculations by accumulating the results of sub­
calculations on the stack and then treating these results as the arguments
in a further calculation.
Example:
To calculate
13^ -
(
17 x 19) + ^
1. Enter 130(2).
The result—169—appears on level 1 of the stack.
2. Enter 17 and press
3. Enter 19 and press (EN
4. Press®.
The product of 17 and 19—323—appears on level 1, and the previous
result—169—is at level 2.
