Arithmetic
Introduction
Chapter 1 introduced you to using the calculator line for doing simple
arithmetic.
Chapter 2 contains additional information on doing
arithmetic calculations.
Using the Calculator Line
You can use the calculator line (line 3) to do arithmetic calculations at
any time, except when the alphabetic annunciator (U) is on. Some-
times the HP-18C displays letters on the calculator line, even though
the alphabetic annunciator is off. For example, the calculator line
might contain:
TOTAL=124.60
Then, pressing 0 2 0 would calculate 124.60 plus 2, and the
HP-18C would display the answer, 126.60.
Simple Arithmetic
Here are some examples of simple arithmetic using the keys 0, Q,
0, [B, and .LJ ( .LJ raises a number to a power). Notice how the
o key completes the calculation. You can also use I INPUT I to complete
calculations.
*
• If the HP-18C is displaying the CFLO or SUM menu, [INPUT I causes the result of the cal-
culation to be
entered into the number list.
