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
C
To turn on the calculator, press
.
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.
OFF
To turn the calculator off, press
.
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.

    FV of -$200.04 is displayed. The HP is programmed so that if the PV is + then the FV is displayed as - and vice versa, because the HP assumes that one is an inflow and the other is an outflow. When entering both PV and FV, one must be entered as negative and the other as positive.

    HP calculates the rate of return to be 12.18 percent. Remember that the HP is programmed so that if the PV is + then the FV is displayed as - and vice versa because the HP assumes that one is an inflow and other is an outflow. When entering both PV and FV values, one must be negative and one positive.

    In essence, each payment is shifted back one period. To analyze annuities due press BEG/END . The word “begin” appears on the screen. Now the HP analyzes the cash flows based on BEG/END beginning of period payments. Change back to end mode by pressing Interest Conversion The following equation is used to convert a nominal rate to an effective rate.

    The CFs from the time line are entered. Now enter the interest rate. I/YR At this point the HP knows the cash flows, the number of periods, and the interest rate. To find the PV, press to get PV = NPV = $377.40.

    The NPV of $220.50 is displayed. Thus, the PV of the cash inflows exceeds the cost of the investment by $220.50. If a negative CF occurs at the end of a project’s life, then the HP may give an error message, indicating that IRR/YR there are two IRRs.

    Linear Regression Beta coefficients can be calculated by using the HP’s linear regression capabilities. The X (independent variable) and Y (dependent variable) values must be entered in the proper sequence, where the X data is on the horizontal axis (market) and Y data is on the vertical axis (stock).

    The value displayed, 1.60, is the slope coefficient, or the beta coefficient. Amortization The HP can also be used to calculate amortization schedules. Example: Determine the interest and principal paid each year and the balance at the end of each year on a three-year $1,000 amortizing loan which carries an interest rate of 10 percent.
