## Questions & Answers

**Q: The calculator misses numbers i put in, so i get the wrong addition. does this calculator let me know if i have missed a number when putting in**
A: That is interesting--how would it know you "missed"?  Mine takes every number I try to use.  Maybe you have a faulty machine.

**Q: Does it retain Memory?**
A: Who ever has this question es because never have been used a calculator to do work.  I am an engineer for many years and I can tell you that nothing is better thant this piece of element.  If you study the calculator you will find two keys M+ and M- do examples and check well the work of these keys and find for yourself how thwy work.  If you ask for my opinion I just simple say that for the price and for the mathematical operation that you can have this calculator is more than wanderful. Besides  this calculator has the ability of correct any error with the back-key. If you didn't buy it yet, do it now.

**Q: how does the percentage button work.  Mine does not seem to.**
A: Honestly - it’s for my 9 yr old who brought it to school. They aren’t using that button, sorry

**Q: What are the dimensions?**
A: It’s 5 1/2 x 4 1/2 “. Great little calculator

## Customer Reviews

### ⭐⭐⭐⭐⭐ Runs on AA battery
*by B***E on 24 June 2026*

Great calculator, nice colour, good layout and big buttons, helpful with shaky hands. I like that it runs on an AA battery 🔋, not button battery, as I use rechargeable ones.

### ⭐⭐⭐⭐⭐ easy to use . perfect
*by J***Y on 15 June 2026*

button size

### ⭐⭐⭐⭐ Very handy basic calculator
*by G***N on 5 September 2026*

A big calculator with a large digital display and large operating keys which make it very convenient to use for some quick arithmetic. Not a device to carry around but rather to leave in a handy location on a desk or table. Requires a battery to be installed but an integral solar cell helps to prolong the life of this. Sold at a reasonable price so overall a basic but useful gadget.
