Just got an idea and a question

In this age of WOW technology, it seems everything is possible. So, here is my tech question: Do you know if there is a Casio calculator simulator. Maybe, just maybe, I can work again on a Casio FX-85v. Won't be the same (it weighed almost nothing, did linear regression in a heart beat, had great features like "constant arithmatic"..etc. ). Constant arithmatic is when you have a list of numbers and you need to subtract 2 from each one of them, or multiply each by 7 , or whatever. I needed to do that repeatedly and it was very fast and simple.

MS Excel will 'excel' in some of these tasks, but not all in such a small package.

So, is there an Android App that simulates Casio calculators ??
