Brain Gainz
Welcome to Brain Gainz! I’m Dr. Tucci, a former college math instructor turned high school teacher with a PhD in Mathematics Education. My mission is to make math accessible, clear, and enjoyable for students worldwide.
Here you'll find instructional videos on high school and college-level math topics—from Algebra 2 to Calculus and beyond. The best way to navigate my channel is to check out my playlists, which are organized by course and topic.
I hope this channel helps you learn math, build confidence, and stay curious. Being smart isn’t just cool—it’s powerful. Investing in your own cognitive growth by continuing to gain knowledge and develop skills is truly what brings people success. Keep flexing those brain muscles and great things are to come!
