I'm having trouble understanding how to add and subtract using different bases.
If I have 742 base 8
- 364 base 8
_______
I think I need to borrow from the 4 to over to the 2 because 2 is smaller than the 4 I'm trying to subtract. When I borrow how much am I borrowing? Do I end up with 8 plus 2 = 10? And then do I subtract 4 from 10 to get 6?
When I count in base 8 what happens after 8?
