5 Picturing Financial Problems
How to approach a Financial Problem
The financial vocabulary of the HP 10bII+ is simplified to apply to all financial fields. For example, your profession may use the term balance, balloon payment, residual, maturity
value, or remaining amount to designate a value that the HP 10bII+ knows as É(future value).
The simplified terminology of the HP 10bII+ is based on cash flow diagrams. Cash flow diagrams are pictures of financial problems that show cash flows over time. Drawing a cash flow diagram is the first step to solving a financial problem.
The following cash flow diagram represents investments in a mutual fund. The original investment was 7,000.00, followed by investments of 5,000.00 and 6,000.00 at the end of
the third and sixth months. At the end of the 11th month, 5,000.00 was withdrawn. At the end of the 16th month, 16,567.20 was withdrawn.

Any cash flow example can be represented by a cash flow diagram. As you draw a cash flow diagram, identify what is known and unknown about the transaction.
Time is represented by a horizontal line divided into regular time periods. Cash flows are placed on the horizontal line when they occur. Where no arrows are drawn, no cash flows occur.
