Maths monkeys give students close race - Telegraph

"A mental arithmetic challenge between two monkeys and 14 university students ended in a close finish."

Well, to be fair, the students were from Duke.

"The new study showed for the first time that, like humans, monkeys can add numbers in their heads."

"Over hundreds of trials involving 40 different addition problems the monkeys had an average accuracy of 76 per cent. The students were correct 94 per cent of the time."
