The frames below give a demonstration of the use of the getprime program.
![]() |
Figure 1 shows the PROGRAM menu along with the NAMES submenu.
We arrived at this by pressing the ![]() ![]() ![]() ![]() |
![]() | In Figure 2 we have started the program. It asks for the number to be put into prime factorization form.
We have pressed ![]() ![]() ![]() |
![]() | Figure 3 shows the resulting prime factorization. In this case ![]() |
![]() | We have pressed the ENTER key and the calculator responds by asking for another number. In fact, this program is set to continually process numbers. It merely restarts after completing each number. |
![]() | In Figure 5 we have entered and completed the factorization of one number and we have entered another number.
First, we entered 10080 and the calculator computed that the prime factorization is
|
![]() | We press the ![]() |
![]() | We press the ![]() |
![]() | As we use the ![]() ![]() ![]() ![]() |
![]() | From the screen in Figure 9 we have two options. We could press the F1 key to
go to edit the program. This option should not be taken. Rather,
we will press ![]() |
![]() | In Figure 10 we have left the program. The screen is left with the information that we had when we quit the program. However, at this point we can not use the cursor keys to move to see any more of the prime factorization line. |
