except the first and last, are of the same value. To solve other types of cash flows, refer to the section below titled, Canadian
Mortgages: TVM Canada , or Chapter 4, Cash Flows .
Figure 1 illustrates a cash flow diagram and how the data in the diagram corresponds to the TVM keys. For a complete list of
keys used for TVM problems, along with their descriptions, see Table 3-1.
