Arrow indicates
direction you
should scroll to

solutions.
Press the

key to view other solutions. Use
[
and

to scroll between all of the solutions for the equation.
Pressing the
t
key at this point returns to the coefficient
input screen.
• Certain coefficients can cause calculation to take more
time.

• If a result is a complex number, the real part of the first
solution appears first. This is indicated by the “R
↔
I
”
symbol on the display. Press
A
r
to toggle the display
between the real part and imaginary part of a solution.
• Any time until you input a value for the final coefficient (
c
for a quadratic equation,
d
for a cubic equation), you can
use the
[
and
]
keys to move between coefficients
on the screen and make changes, if you want.
• Note that you cannot input complex numbers for co-
efficients.
Calculation starts and one of the solutions appears as soon
as you input a value for the final coefficient.
