In case you can't read my attempt at ASCII, it's a five by five grid. The # spaces are places where you insert a single-digit number from one to nine. You must use each number once. The F spaces are where you insert a plus, minus, multiplication or division sign. Nothing goes in the blank spaces. Finally, you may insert brackets anywhere you want. There are two possible solutions, but they're effectively identical. I know that this is probably MUCH simpler than you're used to, but I want to see how fast someone here gets it...
