Calculator Operations with the Orion TI-84 Plus
The only difference between the Orion TI-84 Plus operations and the TI-84 Plus
operations is that the Orion announces or creates audible representations of the
output. Other than that, all other Orion T1-84 Plus operations are exactly the
same as the TI-84 Plus.
The following section is an overview of how the accessible features of the Orion
TI-84 work. For additional information about the operations of the TI-84 Plus,
