data selectively, use reset carefully to avoid losing data needlessly. (See
“
Clearing Calculator Entries and Memories ” on page 6.)
For example, you might reset the calculator before using it for the first
time, when starting a new calculation, or when having difficulty
operating the calculator and other possible solutions do not work. (See
“
In Case of Difficulty ” on page 98.)
