The Corstorphine Primary School, Dunedin, pupil has been ranked in the top 1% of mathematicians in his age group in New Zealand after he gained a high distinction when he scored 98% in an Australian maths exam.
Maths teacher Alistair Banks expects his star pupil will soon overtake him in his ability to rapidly work out maths questions involving large numbers in his head.
"He is just really quick. Basic times tables are a complete bore for him."
Hayden has sat the University of New South Wales international competitions and assessments for schools for the past four years, achieving a high distinction in maths during the past three years.
In 2005, the school "fudged" his age to allow him to sit the exam and he gained a distinction.
Hayden said maths was his favourite subject and he loved statistics.
