Percentage and Calendar

### Percentage Functions

The hp 12c includes three keys for solving percentage problems: b, à, and Z.
You don't need to convert percentages to their decimal equivalents; this is done
automatically when you press any of these keys. Thus, 4% need not be changed to
0.04; you key it in the way you see and say it: 4b.

### Percentages

To find the amount corresponding to a percentage of a number:
1. Key in the base number.
2. Press \.
3. Key in the percentage.
4. Press b.
For example, to find 14% of \$300:
Keystrokes
300
\
14
b
If the base number is already in the display as a result of a previous calculation,
you should not press \ before keying in the percentage — just as in a chain
arithmetic calculation.
