I think these are the last of the schoolbooks we were waiting on. Yay!
Interestingly enough, I did own a copy of Math 7/6 before, because Joshua obviously already worked his way through that book.
But apparently, my decluttering/selling skills got the best of me, because I found no trace of Math 7/6 in our house. Oops.
Fortunately, I found a textbook and solutions manual on half.com for a very reasonable price. And this time I will be sure not to sell them at year’s end.
