## Description

From the manufacturer More About The Product The Casio MX-12B is the upgraded version of the MX-8B , the UK's best selling desk calculator and has a large and clear 12 digit display, it’s dual powered (Solar with Battery Backup) and performs all the main basic functions. It has an extra large ‘+’ key, a square root key, change sign key and also incorporates a 4-key memory function and a Mark up Key (MU).

Review: Not as good calculator as it used to be - Unnecessary double zero buttons replaced with most used single zero button and single zero button pushed to the corner,where you accidently hit double zero. Also manual off button is no longer there. I give 1 star because of this nuisance
Review: No square root key despite blurb stating there is one - Despite the 'more about the product' saying it is an upgrade to the previous model, this does not have a square root key so it absolutely useless for educational use.

## 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

### ⭐ Not as good calculator as it used to be
*by M***N on 14 July 2025*

Unnecessary double zero buttons replaced with most used single zero button and single zero button pushed to the corner,where you accidently hit double zero. Also manual off button is no longer there. I give 1 star because of this nuisance

### ⭐ No square root key despite blurb stating there is one
*by D***S on 6 November 2024*

Despite the 'more about the product' saying it is an upgrade to the previous model, this does not have a square root key so it absolutely useless for educational use.

### ⭐ Careful, odd keyboard layout!
*by A***Y on 5 March 2025*

Who thought it was a good idea to put 00 on the keyboard just where every other calculator I have used just has 0? Didn’t spot it in the advert, I just wrongly assumed that the layout would be the same as every other Casio I have had since 1975.
