They operate identically to the TI-92 series and TI Voyage 200 calculators, and have a Computer Algebra System that allows them to handle symbolic representation.

Compared to the earlier TI-89, the TI-89 titanium is significantly cost reduced, due in large part to the integration of many chips into a custom chip for TI.
