Will Shortz stated that all are possible except 39. Will you be posting solutions? I tried a "systematic" approach (instead of an unrelated series of trials, which did not pan out. To post a system would be interesting.

Was just looking for something new for my "puzzles" bulletin board. I just introduced students the graphing calculators and that the calculators "know" order of operations. So I'm going to have my students do this on the dry erase templates, then show me the solution on their new calculators to drive home the point:)

Not sure if you want it posted where I am stuck- certainly not giving any spoilers on here! But it was fun- I wonder how long it will take my students?
