描述

A short visual showcase of three popular mental math tricks. First, the 1089 reversal trick demonstrates how any three‑digit number leads to 1089 through reversal, subtraction, and addition. Next, a finger method reveals the product of six times seven as 42. Finally, the digit‑sum test shows how adding the digits of any number determines divisibility by nine. Each trick is animated step by step with minimal captions.
