Math Tricks

Overview

A short visual tour of three popular mental math tricks: the 1089 reversal trick, the finger‑multiplication trick for 6×7, and the digit‑sum test for divisibility by 9. The animation demonstrates each trick step‑by‑step, highlighting the underlying pattern so viewers can see why the tricks work.

Phases

#	Phase Name	Duration	Description
1	Intro	~3s	Title "Math Tricks" fades in, then slides up to make room for the first trick.
2	Trick 1: 1089	~12s	Shows a three‑digit number, reverses it, subtracts, reverses the result, and adds to get 1089. Highlights each arithmetic step.
3	Trick 2: Finger 6×7	~10s	Two hands appear; fingers are folded to represent 6 and 7, then the counting method reveals the product 42.
4	Trick 3: Divisibility by 9	~10s	A random integer is displayed; the sum‑of‑digits process is animated until a single digit appears, demonstrating the rule.
5	Outro	~4s	All three results flash briefly, then the title re‑appears with "Try them yourself!" and fades out.

Notes

• Assumptions: The user wants a quick showcase of three well‑known tricks; no specific tricks were listed, so these were chosen for visual clarity.
• All timing is approximate; each step is paced to allow a viewer to follow without narration.
• No persistent on‑screen text except the minimal captions; the visual transformations convey the logic.
• The scene will be a single Scene class; phases are sequenced within that class.
• Transitions between tricks use a quick wipe‑out of the previous visual and a slide‑in of the next.
• Colors: use a consistent palette (e.g., teal for numbers, orange for highlights) to keep visual cohesion.
