Unformatted text preview: Hewlett-Packard 10B Tutorial To begin, look at the face of the calculator. Every key (except one, the gold shift key) on the 10B has two functions: each key's primary function is noted in white on the key itself, while each key's secondary function is noted in gold above the key. To use the function on the key, simply press the key. To access the gold function above each key, first press the key with the solid gold face, which we will call the "gold shift" key, and then press the desired function key. (Note that the gold shift key is near the lower left corner of the calculator keyboard.) Turning the Calculator On and Off To turn on the calculator, press . C Note that the ON key is on the lower left corner of the keyboard—the face of the key has a white "C," while the word "ON" appears below the key. Also, we will designate keys throughout this tutorial by the use of small boxes, as above. To conserve the battery, the calculator turns itself off about 10 minutes after your last keystroke. To turn the calculator off, press . OFF Here we are using the solid black square to represent the gold shift key. Thus, the keystrokes to turn the calculator off are (1) press the gold shift key, and (2) then press the C key. Note that the word "OFF" appears above the C key in gold. Thus, by pressing the gold shift key first, we are activating the gold function above the C key, which is the off function. Also, note that pressing the gold shift key places a little "up arrow" symbol in the lower left corner of the display. Press the gold shift key again and the symbol goes away. The key is a toggle key that switches back and forth between the “regular” and the “gold” functions. is like the typewriter shift key. After you press , look only at gold writing. In this tutorial, whenever you see , the label on the next key is the gold label above the key, not the label on the key itself. Note that the calculator has a continuous memory, so turning it off does not affect any data stored in the calculator. Clearing the Calculator To clear the calculator’s memory, press . CLEAR ALL Hewlett-Packard 10B Tutorial Page 2 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: clears all memory and the display. CLEAR ALL clears the entire display, but not the memory....
