## Questions & Answers

**Q: i wana ask which is better for university eng major this one or the 115es ?**
A: You need to be careful on this one- my son has the ES. Some schools will not let you use the calculators with graphing on them! Check with your engineering dept. Also, you might want a different calculator for your math classes. My son has both, but uses the ES for his engineering.

**Q: Does this Casio replay the equation that you were working on, after it times-out and you turn it back on?**
