Message #1 Posted by Eddie W. Shore on 7 Oct 2007, 9:27 p.m.

This page is aimed for the beginner and/or inexperienced user - aimed to give a quick introduction to the 50g calcuator. The URL is: http://hp50g.pbwiki.com/50g+Basics?l=S

If you want to comment or ask questions, please email me. Thanks!

Have the great rest of Sunday.

Please check the first example problem. It is shown as: 8 + 2 * (16 4) - 2 . This evaluates to 14, not 38. Changing the expression to (8 + 2) * (16 4) - 2 yields 38. Or have I missed something?

Or change the keystroke sequence to:

8 [Enter] 2 [Enter] 16 [Enter] 4 [] [x] [+] 2 [-]

which would reflect the expression as written.

Best,

You say:

"The neat thing is that the Factorial function can accept all real numbers as well as complex ones. In fact the 48 series, 49 series, 50g, 33s, and 35s does this. Just make sure x is not a negative integer."

The 48 series has only the factorial (!) function, and it does not accept complex arguments. And even in the later machines, the "!" function doesn't accept complex arguments; on my HP49G+ and HP50G, it's the "gamma" function that does.

Thank you Rodger, John, and Les:

The edits have been made, and I appreciate the feedback. (Keep it coming)

As far as the factorial section, I changed it say "it can accept all real numbers" and nothing else.

Hi Eddie,
Nice page. Just a couple of things I notice. Concerning the reciprocal key, it divides the number into 1, not by 1. Also, you may want to mention that if there is a command line present, the action will be performed on it (rather than on level 1).
Best regards, Hal
