This is a video of 5 year old Christopher Teh from Penang.
Chris is seen in this video completing 45 arithmetic questions in 1 minute and 16 seconds without error (100% correct) and without a calculator.
Chris’ father (Dr Andy Teh) is a member of Mensa Penang.
Chris attends a kindergarten and abacus training at a local maths centre (where this video was taken). He is now doing the Singapore Primary 2 Maths Curriculum, 3 years ahead of his peers.
In addition, Christopher loves playing chess and beats older kids at the game on a regular basis.
