• In the case of simultaneous linear equations, you can use
f
and
c
to switch the display between the solutions for X and Y (and
Z).
• When there are multiple solutions for a quadratic or cubic equation,
you can use the
f
and
c
keys to scroll the display between X
1
,
X
2
, and X
3
. The actual number of solutions depends on the
equation.
• Pressing
A
while a solution is displayed will return to the coefficient
editor screen.
• The display format of solutions is in accordance with the input/
output format and complex number display format settings of the
calculator’s setup screen.
• Note that you cannot transform values to engineering notation while
an equation solution is displayed.

Matrix Calculations
(MATRIX)
You can save matrices under the names “MatA”, “MatB”, and “MatC”
in matrix memory. Matrix calculation results are stored in a special
Matrix Answer Memory named “MatAns”.
All calculations in this section are performed in the MATRIX
Mode (
