I thought Android came with office type applications.
E.g. Android 4 has QuickOffice, Android 5 has Google Docs
If you want another application just type Office into the Google Play search. Kingsoft Office (aka WPS Mobile Office) is one of the most popular and highly rated.
One of the things to watch out for is whether they store documents locally (i.e. on the device) or in the cloud or both. Google Docs is heavily oriented towards the Cloud. Polaris, seeemingly, tries to do both. Depends what you want....
Not exactly the same as native applications but when I used to have an iPad for college I always used the online Microsoft Office Webapps that are connected to OneDrive. That's a great solution if you're able to be on the Internet at the times when you need to use it. One, it's pretty much the same interface to Microsoft Office 2010/2013 so there's no confusions. Two, it's going to be the most compatible so far less possibility that you created a perfectly laid out document in office on your computer, edit it on your tablet and then open it again on your desktop and ugh there goes your frustration.
