what i mean is, if a question asked you to "show that" or prove how the answer came to  be, what do you write afterwards or is there a symbol to show that you've proven it?

I usually write 'as asked to show' or 'as required'.

But yeah, I wouldn't worry about it too much... I hope they're not too picky about it :)

It's not necessary, but you can write "as required" after "show that" questions, or for proofs, you can write "QED" (used in spesh, don't worry about QED for methods)
