Provide an example of octal subtraction, including borrowing

Subtract 23 (Octal) from 57 (Octal):

markdown Copy code

  57

- 23

------

  34

When subtracting in octal, you start from the rightmost digit and work your way left. If the digit on top is smaller than the digit below, you borrow 1 from the next higher place value. In this case, we had to borrow to subtract 3 from 7 in the rightmost column, resulting in 14 (octal 4) in the answer.
