Citizens Calculator by Everyday, I don't give praise lightly much less for a calculator in which there are so many and they all look alike however yours was one of the only ones that DOESN'T show The work which is a paramount must when doing a Magic Trick using a calculator. The others defeat the purpose by blabbing all the steps done even when those steps are done secretly. Shaking my little peanut head.

I really like how I can choose to control ads. Some of the calculating functions are not smoothly completed is why I held back on providing a 5. I like the look and menu options like sound, appearance, and history.
