The 10-Second Math Trick

Create a fast-paced vertical YouTube Shorts and TikTok lesson revealing a surprising mental-math shortcut for multiplying by 11. Open with a creator-style hook: “Your calculator is about to feel useless.” Use a 24mm lens, overhead angle on a colorful whiteboard, then whip-pan to a confident young teacher writing large, high-contrast numbers with neon markers. Add energetic push-ins, animated arrows, and satisfying marker sounds. Use bright studio lighting with a subtle blue-and-orange color scheme. Show three examples, ending with a timed viewer challenge and a bold comment prompt: “Beat my 5-second score.” Clean captions, punchy edits, and authentic US creator energy.
