Early Number Systems
I. Body Parts
• Hands, fingers, body parts used to
count (e.g., Papua New Guinea).
II. Tally Marks
• Marks on bones/walls (e.g., Ishango
bone, 20,000-35,000 years ago;
Lebombo bone, 44,000 years ago).
• Representation: Group numbers by
landmark numbers starting from the
largest.
• Shortcomings: Requires new symbols
for higher powers of 10 .
II. Base-n Systems
- Landmark numbers: 1, n, n2, n2...
- Example: Base-5 system →
1,5,25,125,
• Advantages: Simplifies addition and multiplication:
product of landmark numbers is another landmark number.
