### đźŹ†Â Top Score Thursday!Â đźŹ†

This weekâ€™s Top Scorer is Wayne Zhao. Wayne is 15 years old from Bridgewater, NJ. He is currently a 10th grader at Bridgewater-Raritan High School. Check out his interview below!

Q: Whats a fun fact about yourself?

A: I got interested in math when I moved and I got a math book from the library as consolationâ€¦Then my calculator broke, and I had to findÂ  without one. For future reference, it equals .

Q: How did you hear of Expii?

A: I think I first heard of Expii at one of the ubiquitous Expii stands at any math contest. Then I got hooked after seeing the clean format of the site, and on the idea that it was entirely written from scratch by users, which meant that the explanations and problems are accessible to me. The weekly problems were just icing on the cake.

Q: How do you use Expii?

A: I mostly use Expii right now for those weekly problems. Nearly every single week thereâ€™s some problem that makes me have to Google some math. Occasionally, I write some explanations or solutions for Expii when I find the time (during the week of Thanksgiving for instance, I wrote solutions for all the problems).

Q: What is your math background?

A:Â  As a high schooler right now, my math background consists of taking every math class in school, competing in math contests, and reading just about every published book on recreational mathematics/mathematical history.

Q: Favorite area/concept of math?

A: My favorite math area invariably changes, but right now it is probably logic or the mathematics of infinity*, maybe because itâ€™s so dense and nitpicky. Other than that, I have always been interested in recreational mathematics/mathematical history (probably from reading Martin Gardner), which may not be math proper, but is definitely worth the time learning about. As for a concept, my favorite also changes. I just learned about Reimâ€™s Theorem, which blew my mind, but I also like the fact that we can prove that there are theorems that are undecidable, which at first seems to prove mathematics is useless, but really just makes it that much more interesting.

Q: Anything else you would like to share about yourself?

A: I love practically every subject, from mathematics to world languages. Plus I read so many books, know (watch?) so much popular culture, and crack so many jokes that someone once told me I was â€ś80% normal, for a mathematicianâ€ť.
