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
(TRCE) to turn on trace and read calculation
results along the graph.
Each press of
C
while trace is turned on cycles the displayed value in the sequence: present
value (
PV
)
m
simple interest (
SI
)
m
simple future value (
SFV
). Pressing
B
cycles in the
reverse direction.
