### Simple Math Puzzle

Hello, everyone! I found this puzzle in a science magazine, and I thought you might like it, although it's a bit less complex then some of the ones you've seen around here.

Code: Select all

`    # / # x # = 1  -   F   F  # F # F # = 22  +   F   F  # + # - # = 3  =   =   =  6  -5   4`

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...

Spoiler:

Code: Select all

`8 /(4 x 2)= 1-   -   +7 + 9 + 6 = 22+   x   /5 + 1 - 3 = 3=   =   =6  -5   4`

That's right. You got it about 7 times faster than I did, too. Then again, I'm just a high-school student.

Including the time it took someone bored enough to do it to stumble upon your topic...
