## The mindset I wish I had during my undergrad

I distinctly remember how guilty I felt on graduation day because I saw all of my math classes as just hoops to jump through. It felt like all I had done was memorize formulas, theorems, and definitions in each class for 4 years, and on graduation day, nothing really stuck. In this talk, I will share what I wish I could've told my undergrad self while we play with elementary math puzzles as inspiration.

## An elementary problem equivalent to the Riemann hypothesis

In this talk, I will speak about my absolute favorite paper from the American Mathematical Monthly which is about an elementary problem equivalent to the infamous Riemann hypothesis which concerns the complex (nontrivial) zeros of the Riemann zeta function.

This elementary problem of Lagarias concerns the sum of divisors function and the harmonic number. If time allows, I will talk about Robin's inequality and superabundant numbers.
