Much of the functionality of the HP 39gII is partitioned into packages called HP Apps. The HP 39gII comes with 15 HP Apps; nine dedi-
cated to mathematical topics or tasks, three specialized Solvers, and three function Explorers. These apps are listed in the tables below.
As you work in these HP Apps, you enter data such as definitions of functions, window settings, and preferences of one sort or another.
The App records all of this data and automatically saves it for you. If you leave the App and come back later, all that data is still there. In
fact, you can save the App with a new name and use the original version of the App for another purpose. The new version, under the
new name, still has all of your data. You can share these apps with other HP 39gII users.
In addition to the apps described above, there are three specialized Solvers, each designed to solve problems of a specific type.

HP App Name Purpose
Function Define functions and explore graphs and table of values
Solve Enter equations and values of known variables, then solve for the unknown variable
Statistics 1-Var Enter columns of data, define 1-variable statistical analyses, compute summary statistics,
and explore statistical plots
Statistics 2-Var Enter columns of data, define 2-variable statistical analyses, compute summary statistics,
and explore statistical plots
Inference Compute and explore hypothesis tests and confidence intervals
Sequence Define sequences and explore graphs and tables of values
