Remember when your teachers used to say that mental math is important because you can’t walk around with a calculator everywhere you go? Never minding the fact that we now do, actually, take a calculator everywhere we go (hello, smartphones), a teenager from India has taken it a step further: He has essentially become a human calculator.
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.”
“This ‘human calculator’ could probably do mental maths quicker than you could type it into your calculator,” Guinness World Records spokesperson Vassiliki Bakogianni wrote in the statement.

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
