I was working on it in a notebook, but there were several pages with pencil markings, so I erased them with an eraser. I checked all the pages, and I've included images of any pages where the writing couldn't be erased. Since there was a name written, I've covered it with a magic marker and applied a label, so you can write your name on it as is. I think the difficulty level is relatively high, but even if you're not attending a cram school, I recommend it because it helps build fundamental math skills through daily calculations.
