India's 'Human Calculator Kid' Shatters 6 World Records In a Single Day
An anonymous reader quotes a report from Gizmodo: Fourteen-year-old Aaryan Shukla cruised through six mental math calculation world records in a single day, according to a Guinness World Records statement published on February 12, earning the well-deserved nickname, "human calculator kid." Specifically, it took Shukla: - 30.9 seconds to mentally add 100 four-digit numbers - One minute and 9.68 seconds to mentally add 200 four-digit numbers - 18.71 seconds to mentally add 50 five-digit numbers - Five minutes and 42 seconds to mentally divide a 20-digit number by a ten-digit number ten times - 51.69 seconds to mentally multiply two five-digit numbers ten times - Two minutes and 35.41 seconds to mentally multiply two eight-digit numbers ten times According to the statement, these are among the most difficult mental calculation world records ever attempted. Shukla's frankly mind-boggling achievement also comes in the wake of another world record he broke in April 2024 at the age of 13: fastest time to mentally add 50 five-digit numbers. It took him just 25.19 seconds. That's an addition every half a second. I wouldn't be surprised if students seeking "shortcuts" in their math homework started phoning up Shukla instead of reaching for their ChatGPT browser tab. Guinness World Records published a video about Shukla's accomplishments on YouTube.
