Hi! I'm a fourth year majoring in Economics and Data Science, and minoring in Statistics. I'm from the Bay Area and went to high school in Albany, the city right next to Berkeley. I enjoy cooking and eating food and recently got very interested in coffee making.

Beside Math 104, this semester I'm taking CS 189 (CDSS offering), STAT 157, and STAT 260A.

• Natural numbers, $\mathbb{N} = \{0, 1, 2, 3, …\}$
• Integers, $\mathbb{Z} = \{… -1, 0, 1, …\}$
• Rational Numbers, $\mathbb{Q} = \{\frac{m}{n} | m,n \in \mathbb{Z}, n \neq 0\}$
• $\mathbb{Q}$ problematic because a bounded subset might not have a “most economical” upperbound in $\mathbb{Q}$
• $\sqrt{2}$ is not a rational number because there exists no such $m, n \in \mathbb{Z}$ such that $\frac{m}{n} = \sqrt{2}$

Have you ever wondered what it feels like for a cow to moo? Probably feels really good.
