It’s shrinking the original so it went from big to small basically. I know Bc the little apostrophe (this thing ‘ ) next to the letters.
For example - ABC is original, A’B’C’ is second, A’’B’’C’’ is the third and so on. Adds an extra mark for every new add on.
I never paid any attention to the scale factor so I can’t help you there, but I hope you pass b, good luck
