In an age when most children are just learning basic arithmetic, Aayansh Bhalla, an eight-year-old student from Delhi, has already demonstrated extraordinary mental math abilities.

On 9 February 2026, at JV Institute of Learning in Pitampura, he set a World Record for the Fastest Time to Solve 1-Digit and 15-Rows Addition-Subtraction Sums Mentally using the Abacus Technique.

He solved 37 sums within five minutes, earning recognition from ACE Book of Records.

What Is the Abacus Technique?

The abacus is one of the oldest calculating tools in human history. While many people associate it with a physical frame and beads, modern abacus training goes much further. Students learn to visualize the beads mentally, allowing them to perform complex calculations quickly in their minds.

This method is widely used in mental math training programs across India and around the world because it strengthens several cognitive abilities, including:

• Faster calculation speed
• Improved concentration
• Enhanced memory and visualization
• Stronger numerical understanding
• Better confidence in mathematics

Students trained in the abacus technique often solve arithmetic problems much faster than traditional methods.

Why 15-Row Calculations Are Challenging

Mental arithmetic involving multiple rows requires advanced concentration. The brain must process numbers sequentially while maintaining accuracy.

Skills involved include:

• Strong working memory
• Fast visualization
• Precise number tracking

Key Highlights of the Record

• 37 sums solved
• 1-digit numbers across 15 rows
• Completed within 5 minutes
• Age: 8 years, 3 months, 24 days
