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.
