In working through complex equations like the one containing six
levels of parentheses above, you really appreciate the value of the

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 calculatorinto 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).
