HONOLULU (HawaiiNewsNow) - Quick: What's 145 squared?
Most of us would grab a calculator to get the answer. But not Luis Esquivel, Jr., a the 5-year-old Hawaii boy who's gaining nationwide fame for his unbelievable math skills.
Esqivel is a kindergartner at Solomon Elementary School, and he recently appeared on the new NBC show "Little Big Shots" with Steve Harvey.
He stunned everyone with his genius-level math knowledge, and had the audience in stitches with his infectious joy.
Harvey asked Luis a series of seemingly impossible math problems, and he nailed every answer.
The phenom's father, Luis, says the family knew his son was different when, at the age of 2, he could do the alphabet both forwards and backwards at almost the same speed.
Luis can now do algebra, but his knowledge goes far beyond that.
"He knows the periodic table, every country in the world, the states," says his father. "His memory is amazing."
His parents believe that all kids can absorb an incredible amount of information at young ages, if they want to. Unlike his 9-year old sister, or 4-year old brother, Luis is constantly asking questions, looking up facts online, and playing number games.
The boy's parents say they don't push him to do it, he just wants to learn.
The Esquivels haven't had his IQ tested, as others urge them to do, and they don't want him to skip grades while he's so young. They want him to enjoy being a kid.
The full video of his appearance on "Little Big Shots" was posted on the show's Facebook page, and in only five days has been viewed nearly 50 million times.
By the way, 145 squared = 21,025
