The 'According to My Calculations' meme captures the essence of the 'know-it-all' trope commonly found in cartoons like Scooby-Doo (Velma) or Jimmy Neutron. It features a character—often wearing glasses or holding a calculator—delivering a supposedly expert opinion that turns out to be absurdly obvious, rude, or nonsensical. The meme evolved from 90s television cliches into a staple of internet culture, frequently paired with the nerd face emoji to mock people who provide unsolicited or overly technical corrections. It is widely used on TikTok and X (Twitter) to highlight financial struggles, social awkwardness, or to simply shut down an argument with a sarcastic display of 'superior' intelligence.
