Using CALC
CALC lets you save calculation expressions that contain variables, which you
can then recall and execute in the COMP Mode (

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
