The cube root example and the percentage addition example (previous
topics) are two simple examples of chain calculations.
For another example, calculate
7 x (12 + 3)
Start the calculation inside the parentheses by finding 12 + 3. Notice
that you don’t need to press
E
to save this intermediate result (15)
before proceeding. Since it is a calculated result, it is saved
automatically
－without using parentheses.
