As well as being able to spell 100 words, Adam knows his two, three, four, five and 10 times tables and the planets.
A boy of two with an IQ of 141 has become Mensa’s youngest member.
Parents Dean and Kerry-Ann said 29-month-old Adam Kirby potty-trained himself after reading a book on the subject when he was one.
As well as being able to spell 100 words, Adam knows his two, three, four, five and 10 times tables and the planets of the solar system.
Dean, 33, from Mitcham, Surrey, expects Adam’s brother, two-month-old Ethan, to be even brighter.
He said: “He will develop at a faster pace as we are more experienced and he has Adam to learn from.”
The test of intelligence and cognitive abilities tailored for younger children suggested the 141 score – 10 more than the reported IQ levels of David Cameron or Barack Obama in the adult test.
