How do you subtract in base eight?

Answer 1

You subtract as with base ten, except that instead of "borrowing" 10 from the column on the left, you borrow 8.

So assume all number below are in base 8.

3 5

- 1 6

--------

You cannot subtract 6 from 5 so you need to borrow.

2313

- 1 6

--------

where the 13 is the borrowed 8 plus the 5 that was already there..

13-6 = 7

and 2-1 = 1

so the answer is 17.
