Began an Open University maths degree at 11 — the boy who corrected his teacher about zero

Asperger's syndrome • BBC documentary subject • Open University maths degree before 15

Cameron Thompson was four years old when he told his teacher she was wrong. She had said that zero was the lowest number there is; the small boy in front of her pointed out that she had forgotten the negative numbers. It was the first sign, in a primary school in north Wales, that this child's relationship with mathematics was not going to fit the timetable. By eleven he had outrun GCSE and A-level and enrolled in a university degree. By the time he was a teenager, a BBC documentary crew was following him to find out what it is actually like to be a so-called boy genius.

Cameron Thompson was born around 1997 and grew up in Wrexham, in north Wales. From the start his mathematical ability was strikingly out of step with his age — the zero anecdote, which became the most-repeated story about him, was simply the earliest public example of a mind that was already thinking structurally about numbers while his classmates were still counting on their fingers.

He was also diagnosed with Asperger syndrome, a condition on the autism spectrum, and the two facts — the mathematical gift and the autism — are inseparable in his story. School was genuinely difficult for him. His family have spoken about how hard the early years were: a child who could outpace his teachers in mathematics but struggled badly with the social and sensory ordinariness of the classroom, and who needed his Asperger's understood before anyone could properly help him.

Academically, he simply could not be contained by the normal sequence. He moved through his GCSEs and then his A-levels far ahead of schedule. The mismatch was so extreme that, in an unusual inversion, he ended up sitting his GCSEs after he had already started his degree-level work — a detail that captures how badly the standard ladder of qualifications fit him.

The degree itself was the headline. At the age of eleven, Cameron Thompson enrolled with the Open University to study for an honours degree in mathematics, doing the coursework by distance learning alongside his ordinary school life in Wrexham. He completed it before he was fifteen, reportedly earning a 2:1 — a strong upper-second-class honours degree — in mathematics, while still young enough to be in school.

Crucially, his family kept him in a mainstream school throughout. He attended a regular high school in Wrexham with children his own age, and he had many of the same hobbies and interests as his peers. The deliberate choice was not to wall the prodigy off in some accelerated hothouse, but to let him do university mathematics in the evenings and be a teenager in the daytime.

In November 2011, the BBC broadcast a documentary about him: 'The Growing Pains of a Teenage Genius' (also released as 'Gifted!'), directed by Barnaby Coughlin. It followed thirteen-year-old Cameron and his family through the daily reality of his life — not a celebration of a wonder-child, but an honest portrait of the friction between an exceptional ability, an autism-spectrum diagnosis, and the very ordinary business of growing up. The film was widely praised, particularly within the autism community, for showing the difficulty alongside the gift.

The Thompson family also turned their experience into a book, 'Gifted! The Story of a Teenage Genius', written with input from Cameron and his parents and sister, in part to help other families navigating a similar combination of giftedness and Asperger's. It described the school struggles, the diagnosis, and the eventual solutions they found — a practical document rather than a victory lap.

Cameron Thompson's significance lies in how visible his story made a particular truth: that profound mathematical talent and a developmental difference like Asperger's frequently travel together, and that the talent does not make the difference easy. The BBC cameras did not find a serene genius. They found a teenager doing university mathematics and, at the same time, working hard simply to manage school — and that honesty is exactly why his story mattered.

“When she said zero was the lowest number, I told her she had forgotten the negative numbers.”
— Cameron Thompson, on correcting his teacher at age four
“The documentary is an honest portrait of a teenage genius with Asperger's syndrome — the difficulty as much as the gift.”
— on the BBC's 'The Growing Pains of a Teenage Genius'
“He flew through GCSE and A-level, then began an honours degree at the age of eleven.”

Cameron Thompson put a human face on a truth that is too often softened: extraordinary mathematical talent and an autism-spectrum condition frequently come together, and the talent does not make the condition any easier to live with. His BBC documentary refused the wonder-child fairy tale and showed the struggle alongside the gift.

His family's approach is its own kind of model. Keeping him in a mainstream school with peers his own age while he did university mathematics by distance learning — and then writing a book to help other families — reframed the prodigy not as a specimen to be accelerated, but as a child to be supported.
