• When you are unsure of how the calculator will interpret the
expression.
There are limits to the number of operators and associated data the
calculator can remember. It is possible to open up to seven parentheses
simultaneously and have six pending operations . In reality, it is only in
the most complex cases that you will approach these limits. If you
attempt to open more than seven parentheses, or if the calculator
attempts to store more than six operations, the display will indicate an
error.
The example below uses four pending operations, and illustrates the order
of operations the calculator follows, according to its entry system.
Example: 5 + (8 ÷ (9 - (2 ÷ 3))) = 5.96
Enter Press
[ON/C]
5 [+] [(]
8 [÷] [(]
9 [-] [(]
2 [÷]
3 [)]
[)]
[)]
[=]
Since the [=] key completes all operations, it could have been used
instead of the three [)] keys. Try to repeat the problem, and press [=]
instead of the first [)] .
When you press [)] , the expression is evaluated up to the nearest open
parenthesis to the left, replacing the element with a single value.
Because of this, you can manipulate the order of interpretation of an
expression according to your needs. You can also check intermediate
results.
