Documentation Conventions
In the body of this guidebook, TI-83 Plus (in silver) refers to the

TI-83 Plus.
All the instructions and examples in this guidebook also work for
the TI-83 Plus. All the functions of the TI-83 Plus Silver Edition and the
TI-83 Plus are the same. The two calculators differ only in available RAM
memory and Flash application ROM memory.
