The Zach Galifianakis Math meme originates from a scene in the 2009 comedy blockbuster 'The Hangover,' where the character Alan Garner (played by Galifianakis) uses his hidden card-counting skills to win at a blackjack table. To represent his mental process, the film overlays complex mathematical formulas and geometric shapes over his focused face. While the original context depicts a moment of brilliance, the internet repurposed the image to represent intense confusion, overthinking, or the struggle of trying to calculate something relatively simple. It has become one of the most recognizable 'confused' templates, frequently used to joke about financial budgeting, social logic, or difficult life choices.
