## Questions & Answers

**Q: Can we change the batteries if we want?**
A: Yes

**Q: Do I have the load the software on to the calculator or is it already set?**
A: The TI-89 Titanium comes pre-loaded with standard software.  If you purchase a used calculator, it may have additional software used by the previous owner.  You can always add and remove programs as you see fit.

**Q: Does it do fractions?**
