The problem is to define something like Pascal's triangle, but with the rows summing to the Fibonacci numbers. Such I call a Fibonacci wedding cake, as it is an elaborate tower made out of multiple tiers.</div><div><br></div><div><div dir="ltr"><div>TeX Hour: Thursday 22 June, 6:30 to 7:30pm BST</div><div>URL: <a href="https://texhour.github.io/2023/06/15/talmo-access-math/" target="_blank">https://texhour.github.io/2023/06/22/access-fib-wed-cake/</a></div><div>Zoom URL: <a href="https://us02web.zoom.us/j/78551255396?pwd=cHdJN0pTTXRlRCtSd1lCTHpuWmNIUT09" rel="noreferrer" target="_blank">https://us02web.zoom.us/j/78551255396?pwd=cHdJN0pTTXRlRCtSd1lCTHpuWmNIUT09</a></div></div><br>Here's something that surprised me. Pascal's triangle can be presented in several ways. For a sighted person the usual way (using Markdown) is:<br><br>||||| 1 |<br>|||| 1 || 1 |<br>||| 1 || 2 || 1 |<br>|| 1 || 3 || 3 || 1 |<br>| 1 || 4 || 6 || 3 || 1 |<br><br>The surprise was the thought that for a blind person (again in Markdown) this left-aligned form might be much better.<br><br>| 1 |<br>| 1 | 1 |<br>| 1 | 2 | 1 |<br>| 1 | 3 | 3 | 1 |<br>| 1 | 4 | 6 | 4 | 1 |<br><br>I'd very much welcome any feedback on access to number triangles. Although the Fibonacci wedding cake is connected to some advanced topics, no special knowledge of pure math is required for this talk. Just an interest in learning about and discovering patterns.</div></div><div dir="ltr">
