Adrienne Hulme, Lead Instructor

I am from Portland, Oregon, and after starting college in Texas, finished my Bachelor's Degree in Math from Portland State University.

I spend most of my time doing photography, but enjoy a variety of other activities that mostly involve being out in the sunshine and/or eating yummy food.

Favorite Number:  52, it's such a lovely number

Favorite Math Joke: The problem with math puns is that calculus jokes are all derivative, trigonometry jokes are too graphic, algebra jokes are usually formulaic, and arithmetic jokes are pretty basic. But I guess the occasional statistics joke is an outlier.

In five years, I will be: Petting dogs all over the world

I love Mathnasium because: I think math skills like logic and problem solving are incredibly useful in life, and I love that Mathnasium is helping erase the negative stigma of math and make it accessible for everyone!

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.
