∠
or
'
a
+
bi
) can be input at the end
of a calculation to specify the display format of the calculation results. The
command overrides the calculator’s complex number format setting.

Using CALC
CALC lets you save calculation expressions that contain variables, which you
can then recall and execute in the COMP Mode (
N1) and the CMPLX
Mode (
N2). The following describes the types of expressions you can
save with CALC.
• Expressions: 2X + 3Y, 2AX + 3BY + C, A + B
i
• Multi-statements: X + Y : X (X + Y)
• Equalities with a single variable on the left and an expression including
variables on the right: A = B + C, Y = X
2
+ X + 3
(Use
Ss(=) to input the equals sign of the equality.)
To store 3A + B and then substitute the following values to perform
the calculation: (A, B) = (5, 10), (7, 20)
