Programming Tutorial: How to Subtract Octal Numbers

Now let try Subtracting number this time to subtract is easy as subtracting a whole numbers

Rules:

1-1= 0
2-1= 1
7-6 =1
5-7 = (just borrow form the next digit if there any, and i dont have any digit to borrowed for the answer would be -2)

Code:


Example:
                               
 765
-136
-------
 627


Note:Because 5 is cannot be divided by 6 we need to borrowed 1 from 6 so it become 5, so 5 will become 13 how do i get 13 this is how (5+8=13)

Thanks for all this programming tutorials, but, don't you think you should be starting from the very start? Just a suggestion.

This is the very start this is not really a programming tutorial but a logic Funtamentals for logic building that every programmer should have
