How to program on a simple calculator?

Question

Programming

I didn’t find an article on this topic, or rather I found it only on a programmable calculator, but I want to “program” a simple calculator, like this:

And so, how can you program a simple calculator ... but by programming I mean a different use of the calculator. ..
Example:
First you enter "1", then the operation "+", and then again "1", and then already "="...
And now by clicking on "=" the number on the screen will increase, a kind of clicker...
And I want more of these things...
PS sorry for the crooked question and maybe stupid, but programmable calculators are boring, but playing around with such a thing is quite fun...

Answer 1

No way. Not only are there 99% of them even nothing to execute the program (because there is a stupid set of logical elements inside), but also if you suddenly find a calculator with a microprocessor, then it is unlikely that it will be possible to flash it.
