To sign 'eighteen', start by forming the ASL number '8' with your dominant hand. Do this by touching your middle finger to your thumb while keeping your index, ring, and pinky fingers extended. Hold your hand up at about shoulder height with your palm facing toward you. Then, quickly twist your wrist outward twice. The twisting motion should come entirely from your wrist, keeping your arm relatively still.
To sign this, point to yourself for 'I', sign 'age' by pulling an 'O' handshape down from your chin, and then sign 'eighteen' by twisting the '8' handshape outward twice.
Sign 'she' by pointing to the person, 'have' by tapping your chest with bent hands, 'eighteen' using the twisting '8' handshape, and finally 'books' by opening your hands like a book.
Sign 'my', 'brother', and then 'age eighteen'. Remember to keep your middle finger and thumb connected securely while you perform the double outward twist for 'eighteen'.

Eighteen uses the ASL number '8'. A helpful trick for the numbers 6 through 9 is to start with your pinky as 6, ring finger as 7, and middle finger as 8. Touch your middle finger to your thumb for eighteen.
For the number eighteen, you should twist your wrist outward twice in a quick, fluid motion. A single twist is sometimes used in faster, fluent conversation, but a double twist is standard for clarity.
You should start the sign with your palm facing inward, toward your body. As you perform the double twist, your wrist rotates so that your palm briefly faces outward.
