Getting Started
This guide is intended to get you started with your new 10bII+ financial calculator. It includes basic information about the many features available on the 10II+
along with example problems. If you require more information about the concepts presented here, refer to the HP 10bII+ Financial Calculator User’s Guide on
the CD included in the package along with your calculator. For more information
about HP calculators, please refer to the training materials available at:
www.hp.com/calculators.
