Compound Interest - Casio FX-7400GII - SOFTWARE VERSION 2-00 User Manual

After configuring the parameters, use one of the function menus noted below to perform the
corresponding calculation.
• {SI} ... {simple interest}
• {SFV} ... {simple future value}
• An error (Ma ERROR) occurs if parameters are not configured correctly.
Use the following function menus to maneuver between calculation result screens.
• {REPT} ... {parameter input screen}
• {GRPH} ... {draws graph}
After drawing a graph, you can press
results along the graph.
