Section 1: Getting Started 15
The v Key. If one of the numbers you need for a two-number function is
already in the calculator as the result of a previous operation, you do not need to
use the v key. However, when you must key in two numbers before
performing a function, use the v key to separate the two numbers.
To place two numbers into the calculator and perform a two number function
such as 2 ÷ 3:
1. Key in the first number.
2. Press v to separate the first number from the second.
3. Key in the second number.
4. Press the function key(s).

Now try this problem. Notice that you have to press v to separate
numbers only when they are being keyed in one immediately after the other. A
previously calculated result (intermediate result) will be automatically separated
from a new number you key in.

Even more complicated problems are solved in the same simple manner—using
automatic storage of intermediate results. (For problems with nested
parentheses, refer to Chain Calculations, page 24.)
Example: Solve (6 + 7) × (9 − 3).
First solve for the intermediate result of (6 + 7):
