INFORMATION

OCTAL SUBTRACTION

To subtract an octal number from another you can follow the steps below.

  • Octal subtraction step 1

    Write the numbers so that the same places are aligned in the same column.

  • Octal subtraction step 2

    Start subtracting numbers from the right-most digit and each time move one digit to the left.

  • Octal subtraction step 3

    In any digit, if the number on top is greater than or equal to the number on bottom, do the subtraction and write the result to the same place.

  • Octal subtraction step 4

    If the number on top is smaller than the number on bottom, move left until a non-zero number is reached on top.

  • Octal subtraction step 5

    Borrow 1 from the first non-zero number and reduce it by 1.

  • Octal subtraction step 6

    Add 8 to one digit right and move to that digit.

  • Octal subtraction step 7

    Continue regrouping and adding 8 to the lower digit until the digit to be subtracted is reached.

  • Do the subtraction and move one digit left.
