## 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"

*by C***L on 4 January 2026*

Exactly as described: a good basic calculator, uses an easily replaceable battery, easy to see display, keys are of good size. Could do without the Grand Total appearing at times (can't be turned off). Good buy for the price.
