 Hi, in this video, I want to explain how to insert a text cell and how to edit some of the text there. So if we're going back to this example, we've already done some mathematical operations here, I might want to explain what I've done. And so I can hover over and I can add a text cell by clicking this button. And anything I type here will give me some formatted text and I have different formatting options here. I can change this, if designated as a heading, bold, italicized, etc. These are all operations that you may already be familiar with from something like Microsoft Word. And so I can explain what I've done. I can say here I've calculated z as x plus, whoops, x plus y. On the right hand side, it gives me a preview of what I've typed. When I move away from this, it just gives me the result. So my explanatory text here and I can always go back and edit this. Again, if I want to stylize it a bit, and italicize some of these mathematical variables, I can do that. I can insert a hyperlink, something that might be useful for some of the homework problems in this course would be to insert an image. If I click on insert image, it gives me a dialogue and I can navigate to anywhere to upload an image here. This is just an example image. And it shows as a bunch of dobbledygook, not a whole lot, but if I, again, navigate away from the cell, I'll scroll to the very top here. If I scroll back down, it does have just the image there. I can always delete what I have by clicking this button here. I can add comments to it. I can also move cells around in the document by using these arrows, which I can move this down below here, but I don't really want to do that because this cell depends on x and y as we've discussed before. And that's about it.
