Here is a quick, fun, and self-indulgent story: I recently started studying for the GRE, and, upon skimming through the workbook, realized that I hadn’t taken a math class in almost nine years. Any confidence I had in my quantitative reasoning abilities quickly dissipated. I’ve since begun taking intro level high school math classes online because I literally have to start from scratch, so when I came upon this viral math problem that’s stumping the Internet, I thought, “Aha! A chance to test my 9th grade math abilities!”
