Alexis Lemaire, PhD student at Reims University, France worked out the 13th root of a random 200-digit number in his head in just 70.21 seconds beating his old record of 72.4 sec.

A well desired title “The Fastest Human Calculator” was earned at London’s Science museum.

The answer of 2407899893032210 was the only accurate solution out of 393 trillion possible combinations.

Alexis said to The Sun: “I’m very proud of my brain. There’s nothing more exciting than being able to function like, or better than, a computer. I live to improve myself.”
