Review: Math Class - Basic calculator for Math Class! This is all you need! Good quality, battery life, works well, portable size, and easy to use!
Review: Its a good replacement for my old fx83 GT plus - Who doesn't love the old fx83 GT plus calculator. Its something you expected to be with you forever. growing old together, experiencing life's highs and lows. However for me, this dream was short lived. After roughly 10 years together my fx83 GT plus got me through school, university and my PhD. But no further. It took me some time to heal but eventually, when I felt ready I started looking again. Then I found the fx115 ES plus. While we are still newly together I get the same sense of ease and commitment to working out problems as with the fx83 GT plus. It works well, adds subtracts and lots of other stuff. If youre in a similar boat to myself and feel its time to move on, the Casio fx-115ES Plus is a good choice.

## 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.
