I can't open an iPages document on a windows comouter?

I send it from my macbook and then when I go to open it on a windows computer at school it doesn't work? However I can access the document from my iPhone 5 that doesn't have pages? Any help?

Pages documents must be opened by the Pages app.
Apple doesn't make Pages for Windows.
Go back to your Mac, open the document in Pages, click "SHARE" at the top menu bar, and choose "Word".
