## Questions & Answers

**Q: Can it handle complex numbers in matrix ?**
A: Yes. .or say within reason. Download the manual from Casio, its free and you dont need to buy calculator.. Look at page 114 and 107. Make sure you download fx-991CW...not fx-991.

**Q: ¿Este artículo tiene garantía?**
A: Good afternoon,

I bought the calculators without a guarantee, but I really don't know if the product has a guarantee, although they should have a guarantee.

Regards,
AC.

**Q: when you turn off the calculator, the calculation history is deleted or not?**
A: The data is deleted when you turn it off.  It's the only thing that keeps it from being the perfect scientific calculator for me.

**Q: is there a ohms law calculator?**
A: Well any calculator can "do" Ohms law. If ypur worried about remembering it, any programming calculator can store formulas for you...Calculated Industries (yellow calculators) makes 2 Electrical calculators, pretty sure both have Ohms law function key.
