Ray Ruhman

Instructor
I grew up here in San Diego so naturally I'm a huge Padres fan and I have to admit that I'm still a fan of the Chargers even though it still hurts that they left! I also love chess and the occasional tennis match. It's really a beautiful thing when playing a tennis game feels like playing a chess game and vice-versa. The two games are so different yet have so much in common it always amazes me. I became interested in math when I was introduced to the concept of imaginary numbers and my fascination grew from there. Favorite Number: My favorite number is 8 because it's always been my lucky number and I can remember as a very young child learning to write numbers and thinking that it was the coolest one. Favorite Math Joke: A statistician almost drowned while attempting to cross a river. By his calculations it was three feet deep on average. In five years, I will be: A better chess player! I love Mathnasium because: It's a great environment that illustrates how fascinating (and useful) mathematics is. Helping others uncover some of the mysteries of math is extremely rewarding.

I'm a San Diego native who moved back down after graduating from UC Berkeley in 2021. I like staying active on my free time either working out or playing sports like basketball or tennis. Favorite Number: 2.71828... because it appears in almost every field you can think of. Whether it's biology, finance, physics, or even your favorite casino game. It always finds it way into the picture! Favorite Math Joke: Do you know what’s odd? Every other number! In 5 years, I will be: Still trying to figure out what I will be in 5 years. I love Mathnasium because: It helps students build foundational skills for one of the most scary and misrepresented subjects in school. Teaching kids that they have the ability to understand and excel at something so terrifying will not only help them in school, but hopefully in other challenges they face throughout their life.

Travis Nielsen

Instructor
I love math and music. Jazz and math rock are my favorite genres of music. Topology and Optimization were especially interesting while I earned my math degree. Favorite Number: 5/4. It’s a really special music signature that many jazz standards are based off of. Favorite Math Joke: Negative. In five years, I will be: Helping math become understandable to a new generation in my classroom and at Mathnasium.

This gets them out of their comfort zone and helps them build motivation both in success, but also in during their rough times.

Tsion-Aduesa Smart

Instructor
On the day to day I’m studying for university and in my spare time I enjoy drawing and designing outfits and characters, listening to music, reading books, and playing volleyball. I’ve always loved math, it allows me to be creative in finding different solutions for the answer! Favorite Number: My favourite number is 2 because it is simply the most perfect and equal number. Halves are a necessity for everything. It's also kind of responsible for the concept of whether things are even or odd. Favorite Math Joke: There are 10 kinds of people - those who understand binary, those who don't, and those who weren't expecting ternary In 5 years, I will be: In five years I will be finishing a Masters in Statistics and Probability, and maybe continuing to teach math as well. I love Mathnasium because: I love Mathnasium because it allows me to bring back the joy of math in people's lives

Kenton Guarian

Instructor
I'm a huge Hozier fan. Favorite Number: √(-1) because it lets us solve every algebraic equation. Favorite Math Joke: If aliens come to Earth and ask us to find the Ramsay number R(5,5) otherwise they destroy Earth, then we immediately devote all computer power on Earth to solve the problem. If those same aliens come to Earth and ask us to find the Ramsey number R(6,6), we launch a pre-emptive war. In 5 years, I will be running code reviews at some software company, hopefully. I love Mathnasium because it requires me to change my way of thinking for each student--not necessarily "how would I do the problem" and more "how can we bridge the final step and reward the learning?"

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
