## Questions & Answers

**Q: Why does the calculator not display decimal answers and only fractions, and why won't it square numbers that aren't perfect squares**
A: Hello, the sd key will change fractions to decimals and back if needed. 
The calculator will simplify square roots that are not perfect squares and if you need a decimal answer then press the sd key and if will convert it to a decimal.

**Q: Is there a comma separator - thousands function for millions and billions,etc. for example 50,000,000,000?**
A: This is not a business calculator - not sure why you'd want a comma separator when you'd be using scientific notation: 5x10^10 for example.

**Q: How is this different than the fx-300ESPLUS2 ?**
A: I am not familiar with the fx-300ESPLU52. You might be able to go to the Casio website to get information on how they are different. This one (the fx-115) has many features which I have not yet used.

**Q: can it used in SAT exam?**
A: I'm a retired hs teacher. I've bought this model two times for my own kids because it met their needs and can be used during standardized exams such as the SAT.
