Bees can learn higher numbers than we thought - if we train them the right way

Bees are pretty good at maths - as far as insects go, at least. We already know, for example, that they can count up to four and even understand the concept of zero. But in a new study, published in the Journal of Experimental Biology on 11th October, 2019, we showed that honeybees are also able to understand numbers higher than four - as long as we provide them feedback for both correct and incorrect responses as they learn.
