The HP Prime advanced graphing calculator was released in September 2013 as a next generation calculator with cutting edge capabilities. It is primarily based on the HP-39gii graphing calculator, but includes a high-resolution color, touchscreen display, an advanced CAS system and unique and innovative control capabilities for teachers and educators. The calculator still provides a number of advanced mathematics users, and can be programmed in HP Prime Programing Language (HPPPL) as well as via custom apps.

This is how to create a link from this page to a new article and how to create that article in a page of it's own.

- Edit this page.
- Create a local link from the appropriate section of this page, about “Article” to the page prime:Article, where Article is the name of the page (must be unique), using Link_Text as the text that the link will be displayed as (that the user can click on). To see the formatting of a local link, you can copy an existing link, such as the “indexing” link in the Programming Documentation section below. Save this page. The Link_Text will be displayed in red indicating that the page doesn't exist yet.
- Click on the red link text. A blank page indicating that this link doesn't go anywhere yet is displayed.
- Click on the pen icon on the right and it will Create the non-existent page and put you in the wiki editor, where you can create your article.
- After you've created your page, you can save it by clicking on the button on the bottom.
- Then, if you go back to the previous page, the Link_Text text is now displayed as green instead of red. If you click on it, it will go to your newly created page.
- Enjoy.
