Problem 3 is where Euler starts forcing us to consider resource limitations. Before, the most straightforward solution worked just fine, even if it used more resources than a less complex algorithm would.

Our first, and certainly not our last, encounter with the Fibonacci Sequence on Project Euler. Before we dive into Problem 2 together take some time to chew on it yourself if you haven’t already.

This is a lovely problem to start with. It has a straightforward brute-force loop solution as well as a nice analytic solution where you can calculate the solution directly without the need for much programming.

How I found Project Euler and pivoted into tech

I’m working to scale one-to-one learning.

In 1984 Benjamin Bloom described the “
Two Sigma Problem", noting that students tutored with one-to-one techniques performed **two standard deviations better** than students in a traditional class.

He also dismissed large-scale one-to-one learning as “**too costly**” and **not “realistic**".

I believe Bloom was right about the effectiveness of one-to-one learning, but wrong about scalability. I’m building tools to prove that **scalable, accessible one-to-one learning is possible today**.
