I might add that Office 365 is also free for students and educators at eligible institutions. Teachers at my school district get it for free, for example (we have a .us domain), as do students with an .edu domain in his or her email address. When you go to this site, you can enter your school email address to get started. If you have questions, a Chat pop-up will appear in the lower right corner of your screen, where you can find out if you are eligible.
If you are not eligible for the free version of Office, this link will provide you with pricing for the various options of Office for both Home and Business users.
One more thing. If you scroll quite a bit further down the same page, you can get to the apps for the free online version of Microsoft Office. For example, the link for the online version of Word is https://office.live.com/start/Word.aspx. The free version, for my money, is definitely worth trying, as is Google's free G-Suite. I just wanted to provide equal opportunity so that no one thinks I work for either company. I don't. Just don't forget to create a free Microsoft account (or a Gmail account if you ever plan to use the Google suite) before even trying anything mentioned in this article.
