Can Monkeys Understand Math? Studies That Will Surprise You

Math is often considered a uniquely human skill, but research suggests that monkeys have a surprising ability to grasp numerical concepts. While they may not be solving algebra equations, studies show that some primates can understand basic arithmetic, number sequencing, and even symbolic representation.

Do Monkeys Have a Sense of Numbers?

Scientists have long been interested in whether non-human primates have numerical abilities. Many studies have found that monkeys can:

✅ Recognize different quantities (e.g., knowing the difference between 3 and 5 objects).

✅ Understand more vs. less (choosing a larger pile of food over a smaller one).

✅ Perform basic addition and subtraction (determining which option results in a greater reward).

Key Studies on Monkey Math Skills

🔬 The “Numerical Competence” Experiment

In a groundbreaking study, researchers trained rhesus macaques to recognize Arabic numerals (1-9) and associate them with different amounts of food. The monkeys consistently chose the larger number, showing they understood numerical value, not just visual size differences.

🔢 Simple Addition and Subtraction

Capuchin monkeys have been tested on their ability to perform basic addition. Researchers gave them a choice between two sets of food rewards, sometimes adding or taking away items. The capuchins could predict which set had more food, suggesting they were performing simple mental calculations.

🎲 Counting and Memory Tests

Japanese macaques were trained to tap numbers on a touchscreen in ascending order. Surprisingly, many completed the task correctly, proving they could mentally “count” and remember number sequences.

How Does Monkey Math Compare to Humans?

While monkeys can understand basic numerical concepts, their math abilities are similar to those of a young human child (around 2-3 years old). They recognize quantities, predict simple sums, and use numbers to make decisions, but they lack the ability to engage in abstract mathematical reasoning like multiplication, division, or algebra.

What Does This Mean for Evolution?

These studies suggest that numerical understanding is not exclusive to humans. Instead, it likely evolved as a useful survival skill—helping monkeys judge food amounts, recognize group sizes, or assess potential threats. This shared ability between primates and humans hints at an evolutionary foundation for mathematical thinking.

Final Thoughts

Monkeys may never be math geniuses, but their ability to understand numbers proves that mathematical thinking isn’t just a human trait. Their skills show how intelligence evolves in different species and highlight the deep cognitive abilities of our primate relatives.
