Study Notes
Early Number Representations
- Numerals were represented differently in the early number systems.
- / (vertical stroke) = 1.
- ∩ (heel bone) = 10.
- 9 (coil/snare) = 100.
- Lotus flower = 1,000.
- Pointed finger = 10,000.
- Tadpole = 100,000.
- Astonished man = 1,000,000.
- Primitive Egyptian writings (hieroglyphics) used pictorial characters that were simplified into conventional symbols over time.
- Examples: 1 = /, heel bone (n) = 10, snare (9) = 100, lotus flower = 1,000.
- Similar symbols existed for numbers like 100,000 and 1,000,000, but they weren't frequently used.
- Example: 532 = 9999000/// , 47 = ∩∩∩∩///////.
- Few people could write, so scribes were called professions.
- Arithmetic operations were developed to compute farm products.
- Addition: 57 + 24 = /////∩∩∩∩∩////// + ∩∩/// means count 10 ones and convert them to a 10 (heel bone) to get ∩∩∩∩////// and ∩∩∩ = 81.
- These symbols took up too much space compared to modern numerals.

- 3 = ///

- 5 = /////
- 6 = ////////
- 7 = ///////
