resulting screen is an input form with input fields for a number of variables (n,

I%YR, PV, PMT, FV).

In this particular case we can give values to all but one of the variables, say,

n = 10, I%YR = 8.5, PV = 10000, FV = 1000, and solve for variable PMT

(the meaning of these variables will be presented later). Try the following:

10 @@OK@@ Enter n = 10

8.5 @@OK@@ Enter I%YR = 8.5

10000 @@OK@@ Enter PV = 10000

˜1000 @@OK@@ Enter FV = 1000

— š @SOLVE! Select and solve for PMT

The resulting screen is:
