Kids train to visualize an abacus for rapid calculations.

 They solve complex math problems mentally, often faster than calculators, by simulating bead movements with finger flicks

According to Grok: “mental abacus training significantly benefits children long-term. Studies show it enhances math skills, working memory, concentration, and problem-solving, with effects lasting decades by improving neural efficiency.

“If the child enjoys it, the time invested is worthwhile for cognitive and academic gains.”
