Description

(Same video with music: https://youtu.be/nF-Gpk0ZpRk) You visit a shrine that has 3 temples. Before each temple, you have to swim in a magical pond. Your path is pond-temple1-pond-temple2-pond-temple 3. Each time you swim, the pond magically triples the number of flowers you are carrying. At the start you have some flowers. At each temple you place an equal number of flowers. And at the end you have no flowers. What is the least number of flowers you could have started with? And how many flowers did you place at each temple? The video presents a solution to the problem. This puzzle has a practical application--it is an example of a financial annuity! The video derives the annuity formula and demonstrates the connection with the magical pond. I also created a version of this video with music: https://youtu.be/nF-Gpk0ZpRk. Let me know if you prefer music in these videos.
