## Questions & Answers

**Q: If I key in the wrong digit can you undo it and key in the correct one? e.g. I mean to enter 12345 but key in 1235 can I undo the 5 and enter 4 then 5?**
A: No you cannot. Let's say you add 3456+ 1234 and instead of 1234 you wanted to enter 1134 press cancel once and enter 1134 and it will still add 3456+1134

**Q: What size is this calculator?**
A: I don't have it with me now, but it is about 15cm long and about 10cm or 11cm wide,  is smooth to use the buttons are very smooth and soft, it has an on and an off button and does the job.  it is not a scientific one but I only use it for book keeping, the screen is nice and big and clear and being white is refreshing on a desk full of boring grey or black office stuff.

**Q: It look very small for desktop**
A: Casio MX -8-B Desk Top Calculator are great to use and very energy save.
It use solar power and battery.
I bought 3 at Amazon.

**Q: Does the screen respond quickly when you press the buttons? I need a fast response calculator..**
A: I have no complaints about the response speed of the keys. Seems to be fairly seemless
