Clearing the HP10BII Calculator

To clear the HP10BII calculator’s memory, press [gold shift] [C ALL].

If we did not press, we would input the data shown on the screen to memory. Clearing the calculator is very important, since unwanted data in memory can result in improper calculations, and hence wrong answers. It is best to get into the habit of automatically clearing memory before starting a calculation. Occasionally, you may purposely want to save data, but, in general, you will be entering all new data, so starting with a clear memory is the safest approach.

There are three different levels of clearing data:

C ALL clears all memory and the display.

C clears the entire display, but not the memory.

< (backspace) clears numbers on the display one at a time if you made a mistake entering data

    I want to be absolutely clear regarding the proper key strokes to clear my 17Bii+ because the Certified Financial Planner national examine requires it. I am not positive "shift" key and "clear all" key clears more than just data. I need to be able to clear any formulas stored as well. Can someone tell me the proper key strokes? seshields@trueblue.com
