Does math give you trouble? Here's some encouragement: Despite their miniature brains, a new study says honeybees can learn basic arithmetic. If they can do it, so can you.

According to a study published this week in Science Advances, scientists at RMIT University in Melbourne, Australia, have shown that honeybees can add and subtract if trained to do so. This discovery helps scientists understand the relationship between brain size and brain power, perhaps knocking birdbrain off the list of perceived slights. Honeybees and humans are separated by more than 400 million years of evolution, so the study's authors say their findings suggest that an advanced understanding of numbers "may be more accessible to nonhuman animals than previously suspected."
