His achievements caught the attention of industrialist Anand Mahindra, who took to social media platform X to express his amazement. "14-year-old Aaryan Shukla from India, last month broke the world record for the fastest time to mentally add 100 four-digit numbers – 30.9 seconds," Mahindra wrote, calling the feat “dazing and bewildering.”
Mahindra’s curiosity about Aaryan’s method
Intrigued by the speed and precision of Aaryan’s calculations, Mahindra sought to understand the secret behind his technique. "I’ve seen some videos before of kids using this technique where the hands are used in some way to aid calculation," he noted. He then asked if there were any resources available to learn the method—not to break records, but for simple business calculations.
"I’m sure Aaryan has a special gift beyond the ordinary, but are there any sites that give a primer on the fundamentals of this technique? Maybe I can use it for some simple, daily business calculations!" Mahindra added.
Aaryan reveals his technique – ‘Flash Anzan’
In response, Aaryan, who has spent eight years perfecting his skills, explained the technique he uses. "Thank you very much, Sir. I am a Mental Calculator (Human Calculator). The technique is called 'Flash Anzan,' where you have to process the numbers flashing on the screen at lightning speed. The base is Abacus. I have been training for the last eight years to achieve this. Thanks!"

Flash Anzan, also known as the chain maths technique, involves adding or subtracting numbers as they rapidly appear on a screen. This method is rooted in the traditional abacus system but requires intense focus and mental agility.
