I’ve recently added Tutor for Numbers for the Mac to the site. The tutorial includes over 50 lesson on the Mac version of Numbers. I have it divided into 8 sections to help keep the tutorial organized. Lessons include how-to’s on creating multiple sheets in a Numbers document, adding text, adding charts, adding photos and video, formatting options for spreadsheets, and sharing options. Everything you need to get started with Numbers on the Mac. Look for the iPad version soon!
