__Financial Mathematics on the Graphing Calculator__

A **graphing calculator** is a handheld device that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. **Graphing calculators** are generally programmable. So the user can create customized programs for science, engineering and education applications. Because they have large displays, it can display several lines of text and calculations at the same time. The **TI 83 Plus** and **TI 84 Plus** also have a slew of built in financial functions similar to those available on advanced financial calculators. On the **TVM **solver by pressing the **[FINANCE]** key and selecting option 1 on the **TI-83,** or pressing **[APPS]** and selecting **[1: Finance]** then **[1: TVM Solver.] **on the **TI-83 Plus/TI-84.** You will see a window that looks like the following except there may be different numbers. N=Number of compounding, I%= annual interest rate,

PV= present value, PMT= payment, FV= future value,

P/Y= payments per year, C/Y= compounding per year,

**Hook Questions**
