14-year-old Indian boy sets six world records in one day

14-year-old Aaryan Shukla has broken six world records in one day, demonstrating his incredible ability in mental arithmetic. The boy was able to mentally add 100 four-digit numbers in 30.9 seconds, 200 four-digit numbers in 1 minute 9.68 seconds and 50 five-digit numbers in 18.71 seconds. Aaryan spent 5 minutes and 42 seconds to divide a 20-digit number by a ten-digit number. The teenager spent 51.69 seconds and 2 minutes and 35.41 seconds to mentally multiply two five-digit and two eight-digit numbers, respectively. He set his first world record about a year ago: he managed to mentally add 50 five-digit numbers in 25.19 seconds. The Guinness Book of Records invited the boy to Dubai, and now he has six more titles to his credit. Aaryan practices mathematics for five to six hours a day to keep his mind sharp. Aaryan's father says that even his family does not understand where the boy's talent for mathematics comes from. The parents only make sure that Aaryan does not get tired and does not get stressed during training.
