**In English there are two numbering systems:**

**Cardinal and Ordinal.**

**ASL Number Systems**

A third way to produce these numbers is to twist the 6, 7, 8, and 9 repeatedly back and forth.

20-29 are produced with the L handshape.

All multiples of the number 11 are made in this way, with a stamping motion, palm down.

The rest of the cardinal numbers are fairly easy.

The palm faces away from the signer.

Numbers 16-19 are made in one of three ways.

Multiples of 10

The numbers 40, 50, 60, 70, 80 and 90 are made with the fingers tapping the thumb in the same repetitive motion as the number 30

Numbers 6-9

Numbers 13-15 are made with the extended fingers together.

Cardinal: 1, 2, 3, 4, 5

Numbers 6-10 are made with the palm facing away from the signer.

Ordinal: 1st, 2nd, 3rd, 4th, 5th

Counting Numbers

Numbers 1-5 are made with the palm toward the signer.

6-9 are made with the tip of the finger touching the tip of the thumb with a slight bounce.

Numbers 11-15 are made with the palm facing the signer with a repetitive motion.

The finger literally “pops out” from the thumb.

The thumb “scratches” the inside of the finger

The number 22 is made with the index and middle fingers in a “stamping motion” with the palm facing downward.

For 20 tap the index and thumb together repeatedly.

21 is made with the L and the thumb while the thumb “wiggles.”

The second way is to sign 16 as 10-6, 17 as 10-7, 18 as 10-8 and 19 as 10-9 with a twist on each one.

Heiroglyphic numerals

For 23, the middle finger wiggles while holding the L handshape steady.

24 is made with the L handshape then the 4.

The number 25 is produced with the L handshape, palm outward, then the 5 or the L handshape with all the other fingers wiggling up and down.

26 is made with the L then 6,

27 is made with the L then 7,

28 is L then 8

29 is L then 9.

The number 30 is made with the 3 handshape with the index and middle fingers tapping the thumb repeatedly. The numbers 31-39 are made with the 3 handshape then the 1, 2, 3, 4, 5, 6, 7, 8, or 9 handshapes, not 30 then 1, 30 then 2, etc.

Babylonian (sexigesimal) based 60

Chinese inscription

The number 70 is made with the pinky extended for clarity while the other fingers tap the thumb.

Numbers 41-49, 51-59, and 61-66 are in a similar way to numbers 31-39.

Numbers 67, 68, 69, 76, 78, 79, 86, 87, 89, 96, 97, and 98 are produced differently.

Arabic Numerals

If the first number is smaller than the second number, there is a small rocking motion inward toward the center of the signer’s body, regardless of hand dominance.

150 would then be 100 then 50. 210 would be 200 then 10. 330 would be 300 then 30. 467 would be 40 then 67.

5076 would be 500 then 576. 615 would be 600 then 15. 722 would be 70 then 22. 880 would be 800 then 80. 979 would be 900 then 79.

Multiples of 1000 are produced with the number 1, 2, 3, 4, 5, 6, 7, 8, or 9 then tapping the 4 fingers in the non-dominant palm.

Multiples of 1,000,000 are produced with the number 1, 2, 3, 4, 5, 6, 7, 8, or 9 then tapping the 4 fingers in the non-dominant palm two times.

Informational Numbers

(or arbitrary) numbers are always made with the palm facing outward.

Informational numbers are example: addresses, social security numbers, Bible Verses, or phone numbers.

Ranking Numbers 1-9 are made with the palm in with the hand moving sideways.

For 10th and above, add the “th”.

If the first number is larger than the second number there is a small rocking motion outward away from the signer’s body.

Multiples of 100 are produced in one of two ways: with 1, 2, 3, 4, 5, 6, 7, 8, or 9 and then the C handshape.

You can also produce multiples of 100 by wiggling the 1, 2, 3, 4, 5, 6, 7, 8, or 9 repeatedly.

Ordinal Numbers

These are made with the palm facing inward toward the signer for 1st - 9th.

For 10th and up, you follow the palm orientation for the counting numbers: then add “th”, even though in English you might say “rd.” or “st” as in 21st.

After 10 years of age, the palm orientation is also the same as the counting numbers. If it is a two digit number have the “first digit” in place on the hand before you touch the chin. Bring the hand out and pause slightly before forming to the second number, not while the hand is in motion.

When using “formal” register, age numbers are formed with the sign AGE then the number with palm facing outward. In informal register during casual conversations, use the numbers mentioned earlier. Older Deaf people will use the move formal signs in all situations. For approximate ages, wiggle the number back and forth to mean “approximately.” For 30 years of age, wiggle the 3 back and forth. For 60, wiggle the 6 back and forth.

Age numbers for persons are signed from the chin during informal or casual conversations.

Counting numbers are used with the index finger of the dominant hand starting on the chin, palm facing outward for 1-5 years of age. Move the number outward to “center” space. Touch the index finger on the chin. Have the number on the hand before you contact the chin. Don’t move the hand into the number.

In ASL there are 14 different numbering systems
