About

My name is Katherine Bellafiore Sanden.  My passion is teaching and learning math and computer science.

Contact me to get in touch.

I chose “Math is Delicious” because I believe math is something everyone deserves to understand, enjoy, and savor.

Through my one-on-one work with students around the country, as well as through this blog, I aim to infect others with an insatiable appetite for quantitative reasoning and creative problem solving.

More about me:

I earned a B.A. in mathematics from Princeton University.  I wrote my senior thesis on Apollonian Circle Packings under the mentorship of Peter Sarnak, and co-authored a paper in the Journal of Experimental Mathematics with Elena Fuchs.

Over the past ten years I have worked with hundreds of students of all levels, in middle school, high school, college, and beyond.

I see mathematics as a beautiful metaphor for life: if you can learn a difficult concept in math, you’re empowered to learn anything–fearlessly.

My specialty is eliminating anxiety around math and replacing it with confidence and fascination.

I also love to see my students get great results. I’ve helped dozens of students raise their grades from C’s and D’s to solid A’s, attain perfect 5’s on the AP Calculus or AP CS exams, ace the national AMC math contest, and succeed in university-level multivariable calculus, number theory, and algorithms courses.

Sometimes I make music videos about math (and other stuff, too).
