Thanks everyone. I guess just there isn't enough materials on how to use it. I even checked you tube. Someone suggested taking a course! Who gives courses on the HP calculator? No one probably. I found the User's Guide, which is better than the User's Manual. So I guess I'll have to perish for months or years till I reach a proficiency level. Thanks for those who answered before. If anyone knows of books or videos on how to use the HP49 or Hp50 please email me. Thanks
