Octal system

Humans use a decimal system because humans have five fingers on each hand. Computers prefer a binary system. A hexadecimal system is usually used as a compromise. But what about an octal system? Simply not using your thums when counting.

0           0      00000        0

1            1      00001          1

2           2      00010          2

3           3       00011          3

4           4      00100          4

5            5       00101         5

6           6       00110         6

7           7       00111          7

10          8      01000        8

11           9      01001         9

12          A      01010         10

13          B       01011          11

14          C       01110          12

15          D       01111           13

16          E       10000         14

17           F      10001          15

20          10     10010         16

The most important advantage is that humans don’t have to shift to new numerals for decimal 11, 12 etc. if they want to leave decimal thinking.
