Numerals

The Na'vi, having four digits per hand, use a base eight (octal) system. This will be familiar to computer geeks, but may take some practice for everyone else.

1. ’aw
2. mune
3. pxey
4. tsìng
5. mrr
6. pukap
7. kinä
8. vol
9. volaw (8+1)
10. vomun (8+2)
11. vopey (8+3)
12. vosìng (8+4)
13. vomrr (8+5)
14. vofu (8+6)
15. vohin (8+7)
16. mevol (2 × 8 = 16)
17. mevolaw (16 + 1)
18. mevomun (16 + 2)

The pattern of accenting and combination continues in this manner.

• pxevol (3 × 8 = 24)
• tsìvol (4 × 8 = 32)
• mrrvol (5 × 8 = 40)
• puvol (6 × 8 = 48)
• kivol (7 × 8 = 56)
• zam = 64 (100 octal)
• vozam = 512 (1000 octal)
• zazam = 4096 (10000 octal)
