How to Sign "18" in American Sign Language (ASL)

In ASL, you make the number 18 by showing "1" and then "8" with your hand. This straightforward way of signing follows the basic rules of American Sign Language, where you combine two numbers to show teens like 11 through 19. The sign is simple - just stick out your index finger for "1" and then make a circle with your thumb and middle finger for "8." People use this number sign all the time when they talk about things like age, dates, or counting stuff.
