Example 5: To discount the sum of 168, 98, and 734 by 20% (800)
• 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
% is pressed stores a result to Answer Memory before the - key is pressed.
