Quanty Math Practice

A useful skill for any quantitative methodologist is fluency with fundamental math concepts. It is crititally important to have a solid working understanding of differentiation, integration, matrix algebra, probability, and many other methods that are relevant in statistical theory and estimation. Unfortunately, I rarely have the opportunity to hone this skill. When I encounter these concepts in the wild, 99% of the time they are being used within the context of an applied proof in some textbook or paper that has already done the work for me. So, I wanted to help myself by creating a small refresher app which gives introductory to intermediate-level math questions and answers. I used AI tools to curate a list of practice problems, and created a framework which would let me embed them in this website. My goal is to complete a few problems each day. Give it a try below!
