Call of Atlantis

I'm stuck on Egypt Level 9=the puzzle piece stuck in the middle, what formula
do I use to get it out?
Thanks

I am stuck on the exact same place and am on my last life. It's one thing to just not have enough time or power tools but it's impossible (and not fun!) to have no clue at all about HOW to align what to get it out! Help pleassssssssse?
