But what makes the British-Nigerian youngster stand out is the fact that she's also a university undergraduate.
Esther, from Walsall, an industrial town in the UK's West Midlands region, is one of the country's youngest college freshmen.
The
talented 10-year-old enrolled at the Open University, a UK-based
distance learning college, in January and is already top of the class,
having recently scored 100% in a recent exam.
"It's
so interesting. It has the type of maths I love. It's real maths --
theories, complex numbers, all that type of stuff," she giggles. "It was
super easy. My mum taught me in a nice way."
She
adds: "I want to (finish the course) in two years. Then I'm going to do
my PhD in financial maths when I'm 13. I want to have my own bank by
the time I'm 15 because I like numbers and I like people and banking is a
great way to help people."
