HP 50g Working with Fractions
The main Calculator Modes form will now be displayed. If the second line does not say STD then press the down arrow key once,
press B below the !CHOOS menu label, use the up or down arrow to select STANDARD mode, and press the F key below the
%OK% menu label to accept the change to Standard mode. The Menu Form should now look as in Figure 4.
It is also worth checking the status of two system flags so that fractions are displayed as they should be. Press the A key below
the !FLAGS menu label to change the flags. Press 5 twice to reach flag 52, the second system flag whose number begins with a 5.
If flag 52 has a check mark by it, press the C key below the $CHK% menu label to uncheck it, so the menu looks as in Figure 5.
This changes from the "one line" display, which shows fractions as in Figure 1 to "many lines" display mode. Now use the down key
to reach flag 79, or press the 7 key eight times. If flag 79 is checked, press the C key to uncheck it, so that its description
says "textbook on". These two settings make the HP50g show fractions on two lines Press the F key below the %OK% menu label
to accept the flag settings. Press F one more time to accept all the changes and quit the Calculator Modes form.
Now the calculator is in Exact mode and Standard mode. If the examples above did not give the expected answers, it is worth trying
them again. The HP50g is also in "many lines" and "textbook" modes now, so the fractions are shown on two lines.
Examples of Fractions in RPN Mode
To try the same examples in RPN mode, the user must first switch from Algebraic mode to RPN mode. Press the H key and then
press B below the !CHOOS menu label, use the up or down arrow key to select RPN mode, then press the F key below the
