Decimal is a counting system that uses 10 digits: 0, 1 2 3 4 5 6 7 8 9.
When 9 is reached, you increase the value of the higher order and reset
the current order to 0: 9+1 = 10

Octal is a counting system that uses 8 digits: 0, 1 2 3 4 5 6 7.
When 7 is reached, you increase the value of the higher order and reset
the current order to 0: 7+1 = 10

Note that is you convert Octal 10 into Decimal you get 8, as 7+1 in
Decimal is 8.

So, if you convert Octal 31 into Decimal you get 25:
Oct 31 = Dec 25.
