## Questions & Answers

**Q: Does this function like a 10key/adding machine? (Meaning not a standard function calculator)**
A: Before retiring, I used calculators, with the paper, for 30 years without looking at the keys & this is the first desktop non paper calculator that I can key in the numbers without looking again. Others didn’t “feel” like the 10 key calculators. This has multiple functions too.

**Q: Is there a button so you can square a number?**
A: There is not a button to square a number, but there is a button to get the square root of a number.

**Q: Website Display display shows 'Financial' but what arrived shows Finacial on the product. ?**
A: I don’t understand ur question... it is a basic calculator with WAY oversized keys, & WAY too big to keep on ur desk....I would not buy it again.

**Q: Does this have a fixed decimal point two places over so I can add up dollars and cents?**
A: it has the ability to add dollars and cents without typing the decimal point. just move the decimal flag to "A"
