Two Japanese nine-year-olds play the word game shiritori while SIMULTANEOUSLY adding 30 numbers flashed in 20 seconds. They are using the technique called "anzan", which is to imagine an abacus in your head. For more info see the book Alex's Adventures in Numberland* by Alex Bellos

*In the US, the book is called Here's Looking at Euclid

I was at the lecture today, this particular part of the talk made my jaw drop! This is unbelievable how a child's brain can comprehend the technique of visualising the abacus in their head and add all the numbers whilst playing a different game. This made me want to buy an abacus straight away. Brilliant talk by Alex Bellos, I recommend his book, very interesting read.

Was at the talk today. This actually made me feel so inadequate and not worthy of taking A level maths ¬.¬
