2) You cannot multiply or divide two num-
bers that have different units of meas-
urement or different conventions,
except for weight and volume.
3) You can multiply and divide numbers
when their units of measurement are
within or between the linear and area
conventions. For example, you can
multiply kilometers by square feet,
which will give you cubic kilometers.
4) The format of the first value you enter
determines the format of the answer.
However, with the
Ç key you can
change to any format you desire, pro-
vided that you maintain convention.
