• Any time until you input a value for the final coefficient
(
c
2
for two unknowns,
d
3
for three unknowns), 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 coeffi-
cients.
Calculation starts and one of the solutions appears as soon
as you input a value for the final coefficient.
