Concerning grammatical arrangement?

Question

I propose the following structure to describe a process that takes place only by the reader's inclusion.

When (A) is done, and (B) be done, does (C) get done.

An example,

When a calculator is turned on, and the keys "8", "+", "8", and "=" be pressed, does the result "16" get shown.

Is this grammatical arrangement agreeable?

Answer 1

While operating a calculator, if the keys 8,+,8 and = are pressed,will

the total(0r result) 16 appear on the screen?

Answer 2

No, because "be pressed" doesn't make sense in this sentence, and nother does "get shown".

"When a calculator is turned on and the keys "8" + "8" and "=" are pressed, the result "16" is shown.

The whole idea is just awkward; I'm not sure what you're trying to do.
