Hello, and welcome to the forum!
The reason that this isn't returning anything is because the title tag should go in the head section of an HTML document, not the body. The title is the text you'd see on a page's tab or when you look at a window's title. This page's title is "Why is HTML Not Working? - Programming". In addition, the slashes in your closing tags should be before the tag name, like </body> rather than <body/>.
If you want the text to appear on the page, you should use an h1, for heading 1, tag instead of a title. That would look like this:
If you did mean to use the title tag, then you should be putting it in the head section of the document, as I did here:
Hopefully this helps, and I can definitely help you more if this didn't make sense!
