Parker H.

Parker grew up in Colorado with a deep love for math and a fascination with how formulas and methods connect to real life. He believes math only matters if you can apply it—a perspective he shares with students every day at Mathnasium. His favorite number is e, because it’s the only function that is its own derivative and integral. 

Outside of Mathnasium, Parker enjoys working with computers, listening to music, and diving into a good story. Fun fact: he can raise either of his eyebrows independently!

Jacob H.

I've taken everything up to Calculus 1, and I'm currently taking Intro to Statistics. I've published a book, "Jake's Door," which has become an Amazon Bestseller. I've also been a member of a few groups in high school, including: Out knowledge bowl team; we won an award at a regional competition, chess club, and The school's gifted and talented group. I'm a volunteer for Hope Worldwide to help people in need, like serving the homeless and I'm an active member of my church ministry, where I volunteer with A/V equipment. I love art, mainly drawing on pencil and paper. I've filled up nine sketchbooks over my life and the tenth one's almost full! It's my creative outlet, I love making characters, worlds, and stories. I especially like drawing comic strips; writing humor and jokes is very fun for me. Recently, I've been branching out into digital art and animation, it's been very fun. I like walking and spending time outdoors, especially when I've got a good song on. I like to go on hikes/bike rides, see beautiful views, and catch a nice breeze. I'm also very fond of logic puzzles; I enjoy that sort of problem solving, and getting that "a-HA!" moment when you solve them is super fun. 

Fun Fact: If I have to pick one fact, I'd choose publishing "Jake's Door," that's an accomplishment I'm very proud of. The book made over $10k, and I made it when I was only 14 years old! 

Education: I graduated from high school at Colorado Early Colleges last year with an associate's degree. I'm currently a junior in college at CU Denver, and I'm hoping to major in computer science. 

Favorite Number, Why: Gonna have to go with 1 here. You see a 1 in a math problem, you know it's gonna be easy. That you'll be safe. Everything's gonna be alright. 

Why I love Mathnasium: I love to help people, I love math, and I've been told that I'm very good at explaining complicated things to people, so I believe math tutoring would be a great job for me. It's what I love doing, but as a job!
