In working through complex equations like the one containing six
levels of parentheses above, you really appreciate the value of the
Hewlett-Packard logic system. Because you calculate one step at a
time, you don’t get ‘‘lost’” within the problem. You see every
intermediate result, and you emerge from the calculation confident of
your final answer.
Statistical Functions
Accumulations
Pressing the key automatically gives you several different sums
and products of the values in the X- and Y-registers at once. In order to
make these values accessible for sophisticated statistics problems,
they are automatically placed by the calculator into secondary storage
registers Rg, through Rgg. The only time that information is automati-
cally accumulated in the storage registers is when (or 2-)) is
used. Before you begin any calculations using the 23 key, you should
first clear the protected secondary storage registers by pressing {1
followed by £ [=3).
