The line comes from Futurama, the animated sci-fi comedy, spoken by Professor Farnsworth, the show's eccentric elderly inventor. Fans clipped his dramatic dread of mathematics because it perfectly sums up everyone's reluctance to do sums, and it spread across meme pages and reaction compilations as a go-to response to anything involving numbers. Like other reaction clips such as You What, it thrives as a short punchline rather than a full scene, which is why it still pops up under homework videos, budgeting skits and puzzle streams years later.
