* As shown here, if you want to use the current Answer
Memory value in a mark up or discount calculation, you
need to assign the Answer Memory value into a variable
and then use the variable in the mark up/discount
calculation. This is because the calculation performed
when
v
is pressed stores a result to Answer Memory
before the
,
key is pressed.
