Certainly a case may be made out for binary arithmetic. Some computers
such as the IBM 704 and the DEC computers operated inteernally in binary.
Writing a binary number in octal (scale of 8) is a trivial change. Octal
digits can be represented by 3 bits, while a decimal digit requires 4 bits.
Octal addition table:
1 2 3 4 5 6 7
-------------------------------
1 | 2 3 4 5 6 7 10
2 | 3 4 5 6 7 10 11
3 | 4 5 6 7 10 11 12
4 | 5 6 7 10 11 12 13
5 | 6 7 10 11 12 13 14
6 | 7 10 11 12 13 14 15
7 |10 11 12 13 14 15 16
Octal multiplication table:
1 2 3 4 5 6 7
--------------------------------
1 | 1 2 3 4 5 6 7
2 | 2 4 6 10 12 14 16
3 | 3 6 11 14 17 22 25
4 | 4 10 14 20 24 30 34
5 | 5 12 17 24 31 36 43
6 | 6 14 22 30 36 44 52
7 | 7 16 25 34 43 52 61
Unfortunately 1/3 is a repeating fraction in both the scale of 8 and the
scale of ten:
�Radix 8; 1/3 = 0.252525....
Radix 10 1/3 = 0.333333....
Radix 12 1/3 = 0.4
