Grace
Instructor
Hi! I’m a math student at CU Denver with a love for numbers, fashion, and cooking—there’s no better feeling than creating the perfect dish!
Mathnasium feels like home because of the amazing students and supportive environment. Seeing their positivity and dedication makes every day rewarding.
My favorite number is 139—it follows a perfect pattern with powers of 3 and is prime (just like 3!). Outside of math, I enjoy playing the ukulele (self-taught!) and writing songs. In five years, I’ll be graduating with my Master of Science in Mathematics!
Alex
Instructor
About me: My name is Alex and I am currently a junior at East High School. Throughout my academic journey, I have always loved math. In elementary school I helped run the Math Olympiad team, In middle school I took advanced math classes and studied on the side, and in high school so far I've taken the hardest classes I can. Apart from loving math, I play Ultimate Frisbee, run Cross Country, and absolutely love to play music (mainly piano and saxophone, but I've been trying to learn the drums recently as well). In my free time I like to spend quality time with friends and family.
Why I love working at Mathnasium: I like working at mathnasium because I love the feeling of helping someone understand a new concept or think about things in a different way. I love when I get to see that Aha moment that happens when a student finally understands something they've been struggling with.
Favorite number: My favorite number is 104,729 because it is the 10,000th prime number, and I think it rolls off the tounge nicely.
Fun fact about myself: A fun fact about me is that I can solve a Rubik's cube in about 30 seconds.
In 5 years I'll be... I will be a senior in College hopefully close to obtaining a degree that I'm excited about and ready to continue my life after college.
