The humble honeybee can use symbols to perform basic maths including addition and subtraction, shows new research published today in the journal Science Advances. Despite having a brain containing less than one million neurons, the honeybee has recently shown it can manage complex problems – like understanding the concept of zero. Honeybees are a high value model for exploring questions about neuroscience. In our latest study we decided to test if they could learn to perform simple arithmetical operations such as addition and subtraction. Addition and subtraction operations As children, we learn that a plus symbol (+) means we have…
