How determine largest reflected number

Question

I was trying to determine maximum number from list of given integer in problem 8 here (page 5).

So as you see, there are 5 written numbers on paper, and on the wall there is a hanging mirror. We should determine which row contains the largest integer.

Answer 1

The numbers (as we see them in the mirror) are $$8800008$$ $$8008808$$ $$8000088$$ $$8888808$$ $$8008008$$ A mirror flips left and right, so the actual numbers on the paper are $$8000088$$ $$8088008$$ $$8800008$$ $$8088888$$ $$8008008$$ Clearly, the middle one (row number 3) is the biggest.
