Go to your Application Manager, Download, System, and look for "Easy Debian". Install it. Then go to your menu, find "Deb Img Install" and run that. Be patient as the image downloads and extracts. When you have the image, then run the red diamond icon and when you have the blue swirl desktop, press the menu button in the top left. Find "office" and you should see the Open Office suite in there.
