Arithmetic Session 7 and 8 Homework missing?

In which video does Greg go over the homework questions posted below Arithmetic Session 7? In Arithmetic Session 8, he just moves on to new problems, not reviewing Session 7’s HW. Also, in Arithmetic Session 8 at 1:03:53, Greg says he’s posting a few questions to the discord (which he normally posts below the video) (Questions 11, French francs vs USD) but I can’t find them below the Arithmetic Session 8 video. I skimmed over Session 9 and see that he reviews Question 11, but the French francs vs USD question (Session 8 1:03:57) disappears? Can someone direct me to where the Session 7 and 8 questions are and where they are gone over? Thanks!!

I am also having this issue and cannot find where these questions are reviewed

bump. I also can’t find these. Any update?
