(Wildberger &amp; Rubine, The American Mathematical Monthly, 2025)<\/p>\n<p>As you might expect, understanding how this works isn&#8217;t easy for the non-algebra geniuses amongst us. Essentially, polynomials are equations that include variables raised to non-negative powers (e.g. x3). When those powers are five or above, that&#8217;s a higher-degree polynomial.<\/p>\n<p>Mathematicians have figured out how to solve lower-degree versions, but it was thought that properly calculating the higher-degree ones <a href=\"https:\/\/en.wikipedia.org\/wiki\/Abel%E2%80%93Ruffini_theorem\" target=\"_blank\" rel=\"noopener\">was impossible<\/a>. Before this new research, we&#8217;ve been relying on approximations.<\/p>\n<p>Wildberger and Rubine took a new approach to the problem, which is based on <a href=\"https:\/\/en.wikipedia.org\/wiki\/Catalan_number\" target=\"_blank\" rel=\"noopener\">Catalan numbers<\/a>. These numbers are used in advanced number counting and arrangements, including counting how many ways polygons can be subdivided into triangles.<\/p>\n<p>By extending the idea of Catalan numbers, the researchers were able to demonstrate that they could be used as a basis for solving polynomial equations of any degree. Part of the clever method involved extending polygon counts to other shapes besides triangles.<\/p>\n<p>It&#8217;s a <a href=\"https:\/\/www.sciencealert.com\/math-genius-finally-discovers-easy-way-to-solve-quadratic-equations-after-4-000-years\" target=\"_blank\" rel=\"noopener\">departure from the traditional method<\/a> of using <a href=\"https:\/\/en.wikipedia.org\/wiki\/Nth_root\" target=\"_blank\" rel=\"noopener\">radical expressions<\/a> (like square roots and cube roots) to solve equations like this, instead relying on <a href=\"https:\/\/en.wikipedia.org\/wiki\/Combinatorics\" target=\"_blank\" rel=\"noopener\">combinatorics<\/a> \u2013 counting numbers, fundamentally, but in increasingly advanced ways.<\/p>\n<p>&#8220;The Catalan numbers are understood to be intimately connected with the quadratic equation,&#8221; <a href=\"https:\/\/www.unsw.edu.au\/newsroom\/news\/2025\/05\/mathematician-solves-algebras-oldest-problem-using-intriguing-new-number-sequences\" target=\"_blank\" rel=\"noopener\">says<\/a> Wildberger.<\/p>\n<p>&#8220;Our innovation lies in the idea that if we want to solve higher equations, we should look for higher analogs of the Catalan numbers.&#8221;<\/p>\n<p> frameborder=&#8221;0\u2033 allow=&#8221;accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share&#8221; referrerpolicy=&#8221;strict-origin-when-cross-origin&#8221; allowfullscreen&gt;<\/p>\n<p>The researchers put their new algebra up against some well-known polynomial equations of the past, including a famous cubic equation studied by <a href=\"https:\/\/en.wikipedia.org\/wiki\/John_Wallis\" target=\"_blank\" rel=\"noopener\">John Wallis<\/a>. The numbers checked out, validating the new work.<\/p>\n<p>Wildberger and Rubine didn&#8217;t stop there. They also discovered a new mathematical structure called the Geode, which ties in with Catalan numbers and seems to act as a foundation for them. This Geode could form the basis of many future studies and discoveries, the researchers say.<\/p>\n<p>As the approach taken here is so different to what&#8217;s gone before, there&#8217;s the potential to rethink many key ideas that mathematicians have long relied on for computer algorithms, the way data is structured, and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Game_theory\" target=\"_blank\" rel=\"noopener\">game theory<\/a>.
