Here is how to read base 3/2 with the tiles:
The mapping from tiles to base 3/2 digits is as follows:
- Tiles 0 and 1 map to digit 0/2
- Tile 2 maps to digit 2/2
- Tile 3 maps to digit -1/2
- Tiles 4 and 5 map to digit 1/2
Here: ‘2515524’ (lowest significant digit at the end) becomes:
1/2 + 2/2 (3/2) + 1/2 (3/2)^2 + 1/2 (3/2)^3 + 0/2 (3/2)^4 + 1/2 (3/2)^5 + 2/2 (3/2)^6 = 20
