Monkeys’ mental maths almost matches humans’

A MENTAL arithmetic challenge between two monkeys and 14 university students almost ended in an embarrassing draw, it was revealed yesterday.

The pair of female rhesus macaques, Feinstein and Boxer, were as quick at working out sums as the students and nearly as accurate, scientists in the US found.

Both “teams” found certain problems more difficult than others in very similar ways.
