1 HP 10BII Calculator The HP 10BII comes complete with a users guide that explains in detail how this calculator works. The guide also illustrates most of the calculator’s common applications. It is a great resource, so it is wise to keep the user’s guide handy. Hewlett-Packard Company has graciously given permission to use the User’s Guide and a photo of the HP 10BII. Hewlett-Packard has asked that the following be included in this supplement. (It’s a legal thing.) Photos are the courtesy of Hewlett-Packard Development Company, L.P. Hewlett-Packard does not warrant the accuracy or completeness of the material in this publication and disclaims any responsibility for it. Please note the key I have labeled as the 2 nd key. HP calls this the shift key. It is used to change the function of the various “function” keys on the calculator. Function keys have a white function and an orange function. To utilize the orange function, the 2 nd or shift key must first be pressed. Note that the display will show the word shift when the 2 nd key is pressed. This simply means you are using the orange functions rather than the white functions. Try it. Turn the calculator on by pressing the white ON key. Turn the calculator off by pressing the 2 nd key followed by the white ON key. The calculator turns off because you are using the orange function which happens to be OFF.

2 Since most calculations are dollars and cents, it is a good practice to display the results to two decimal places. This is accomplished by pressing the following keys; 2 nd DISP (white “=” key) and 2. The display will show 0.00. Unless otherwise instructed, your calculator should be set to 2 decimal places. It is important to note that the calculator’s register (memory) will retain the exact results of a calculation, regardless of the number of decimal places displayed. The calculator register will retain at number such as 2.899523525689 even though the display shows 2.90. If you wish to compute precise answers it will be important to use the number that resides in the calculator’s registry rather than rekeying a number as 2.90 instead of leaving the true value in the register. It is always a good idea to clear the display prior to starting a new operation. Press the “C” key to clear the display and current register. After pressing the C key, the register will display 0.00.
