BigDecimal is a wrapper class in java.math.  Like other data type
wrapper classes (like Integer, Long, Double, etc.) you don't use it
directly with numeric operators.  Numeric operators expect primitive
data types like int, float, double.

Look at the methods associated with BigDecimal.  There are things like
BigDecimal.multiply(), etc. that you would use.
