Constant: In a simple multiplication problem, the first number entered is automatically taken as the
constant. When ? or ' is used more than once in a sequence ending with a multiplication, the
constant is a composite multiplicand. This number is shown in the display the last time ? is pressed.
In a division problem, or in a mixed sequence ending with a division, the last number entered is taken
as the constant. The constant is cleared by entering a new multiplication or division problem, or by
pressing 2.
