The Story
Join Mable Mathis as she plays a multiplayer online math game with her friends from around the globe: Angus from Australia, Sadia from Pakistan, Hyejin from South Korea, and Norma from El Salvador. Their goal is to defeat the math monsters' order-of-operations problem. Mable discovers that the acronym "Please Excuse My Dear Aunt Sally" is not a universal concept. Angus uses BIDMAS, Sadia uses BODMAS, Hyejin uses ์ฌ์น์ฐ์ฐ ์์, which means "follow the order of operations", and Norma uses PEMDAS. Through her search for Aunt Sally, she realizes that mathematics can be correct even when taught differently, because math is a universal language - no matter where you are in the world.
