Web pages that exploit JavaScript to explain and calculate permutations and combinations.

Brief Explanation

Some of the toughest math problems involve simple questions like “how many?” The simplest examples of these involves rearrangements of the elements of small (or large) sets. When order matters, these rearrangements are called permutations; when it doesn't they are combinations.

You can visit the pages in order, by following the links at the tops and bottoms of the pages. But you can also visit them in arbitrary order. In the section below, there are links for each page, so you can jump to them directly.

These two pages merely scratch the surface. I look forward to creating more pages that use the power of HTML5 and JavaScript to provide interactive demonstrations of cool things. Stay tuned!
