|Calculation Type||Calculation Formula||Calculation Method and Key Operations|
|A × B100||What is B percent of A?
|AB × 100||What percent of B is A?
|A + A × B100||What is A increased by B percent?
|A - A × B100||What is A decreased by B percent?
|Rate of Change (1)
|A + BB × 100||If A is added to B, by what percent does B change?
|Rate of Change (2)
|A - BB × 100||If B becomes A, by what percent does B change?
Example 1: To calculate 12% of 1500 (180)
Example 2: To calculate what percentage of 880 is 660 (75%)
Example 3: To increase 2500 by 15% (2875)
Example 4: To decrease 3500 by 25% (2625)
Example 5: To decrease 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.
Example 6: 300 grams are added to a test sample originally weighing 500 grams, producing a final test sample of 800 grams. What percent of 500 grams is 800 grams? (160%)
Example 7: What is the percentage change when a value is increased from 40 to 46? How about to 48? (15%, 20%)
