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
• 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
(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)
