Why Do We Count on Fingers?

We use our fingers to count because they’re right there! When you were a kid, you probably used your fingers to count things like toys or cookies. That’s easy, and fun! But why do we still use this method today? Well, it turns out that most people in the world use base-10, which means our number system is built around 10 digits (like 0 through 9). And guess what? We have 10 fingers. That’s not a coincidence, we counted on our hands long before we had numbers written down.
