 I want to take a second just to show you something. This is my program files folder inside my computer. The reason why is because you might notice that I have this thing called Microsoft Office. If I dig in there, I want to point out there's nothing in here that says Excel just yet. Everything is pretty generic. Clipart, very generic. But Office 15. If I go into there and I dig a little deeper, it's only here that I start to see for example, Microsoft Excel. But I also see Microsoft Access. I actually also see Publisher. Outlook is even in here. One note is even in here. PowerPoint, Word, Visio. All of these programs that we use inside of the Microsoft Office week, they're actually all the same program, just a different view of it. And the reason why this is important is because you might notice if you've played around with Word or PowerPoint a little bit is really the same things that are in that program or those programs are inside of Microsoft Excel. Take a look at our home tab over here. This home tab has all of the same formatting abilities of Microsoft Word PowerPoint. The only difference is subtle. For example, we have a number section where I can change this percentage from a percentage to a dollar sign. Obviously, in the context of it being taxed, that doesn't make any sense. But this is where things change just a little bit. But I can change my fonts as necessary. Say, for example, I wanted these to stand out a little bit more. One of the things I can do is I can click, hold and drag to highlight all three of them. And then I can set them to be bold, maybe give them a background color where I highlight them with a little bit of a dark blue. And then maybe I can change the color of my text to white. Suddenly, I've given it a little bit more formatting to make it a little bit more presentable. I can even go a little bit further. I could add in say an underline a bottom border after my tax. And so suddenly I can see that these are my options of input. And here is my calculation.
