Bug: HP Prime can't do Log's

[Han]

Perhaps the most indispensable lesson for any new user is the [Help] key. Typing any command on the command line and pressing help will bring up its help. Secondly, the catalog is equally important. So if one does not know whether a certain command exists, it is possible to try to guess the command in the catalog.

[Toolbox] -> select "Catlg" from the menu at the bottom of the screen

While in this catalog, just type out what you think might be a command name. For example, typing SOL would bring the catalog to the SOLve command. Then pressing help while that entry is highlighted will bring up the help for that command.
