Your HP-10C:
A Problem Solver
Your HP-10C Programmable Scientific Calculator is a powerful problem solver
that you can carry with you almost anywhere. It handles problems ranging from
the simple to the complex, and can remember data. The HP-10C is so easy to
program and use that it requires no prior programming experience or knowledge
of programming languages.
An important new feature of your HP-10C is its extremely low power
consumption. This efficiency is responsible for the lightweight, compact model
design, and eliminates the need for a cumbersome recharger. Power
consumption in the HP-10C is so low that the average battery life in normal use
is 6 to 12 months. In addition, the low-power indicator gives you plenty of
warning before the calculator stops functioning.
The HP-10C also helps you to conserve power by automatically shutting its
display off if it is left inactive for several minutes. But don't worry about losing
data—any information you have keyed into your HP-10C is saved by
Continuous Memory.
Your Hewlett-Packard calculator uses a unique operating logic, represented by
the v key, that differs from the logic in most other calculators. The power
in HP calculator logic becomes obvious through use. Later we will cover the
details of this logic, but right now let's get acquainted with v in
performing calculations.
For example, let's look at the arithmetic functions. First we have to get the
numbers into the machine. To do this, key in the first number, press v to
separate the first number from the second, then key in the second number and
press +, -, * or ÷. Answers appear immediately after you press a
numerical function key.
To get the feel of your new calculator, turn on the
display by pressing the = key. If any nonzero
digits appear, you can press ` to clear the
display to 0.0000. If four digits are not displayed
to the right of the decimal point, press ´•
4 now so your display will match those in the
following problems. (Displays illustrated in this
handbook are set to the • 4 display setting
unless otherwise specified.).
