Steps to Perform Arithmetic Operations on Octal Numbers

Go through the following simple steps to perform arithmetic operations on any two octal numbers. You can have a loook at the procedure of how to add, subtract, multiply and divide the octal numbers in the following sections.

  1. Addition:
    • Take any two octal numbers.
    • Octal numbers are from 0 to 7.
    • Write numbers one by one.
    • Perform addition operation between two numbers from units place to left wards.
    • For example, add 1+7 is equal to 10 which means 1 as carry and 0 in the answer place.
    • Adding of remaining numbers which gives result less than 7 remains same.

    Example Question: What is 12 + 37?

    Solution:

      1

     1 2

    + 3 7

    = 4 1

    12 + 37 = 41

  2. Subtraction:
    • Write two numbers one by one at different lines.
    • If the number 1 is less than number 2, then borrow from the next number.
    • Subtract the numbers.
    • Add result at the next line.

    Example question: Solve 321 - 46?

    Solution:

     3 2 1

    - 0 4 6

    = 2 5 3

    321 - 46 = 2 5 3

  3. Multiplication:
    • Take any two numbers and write them one after other.
    • Multiply the first digit of second number with all the digits of first number.
    • Continue multiplication of all digits of second numbers as the above step till none left.
    • Add zero at the first place of second row.
    • Perform the addition of obtained numbers to get the result.

    Example question: Solve 32 x 25?

    Solution:

        3 2

       x 2 5

      2 0 2

    + 6 4 0

    = 1 0 4 2

    32 x 25 = 1 0 4 2

  4. Division:
    • Take divisor and dividend.
    • Write the divisor table.
    • Check to find the exact dividend in the divisor table.
    • If not there, check which number in the divisor table is near to the dividend.
    • Give the multiplication number at the quotient side and obtained number under dividend.
    • Subtract those numbers.
    • Continue the process till we left nothing or number is less than the divisor.
    • Write quotient as the answer.

    Example question: Find 3443 / 7?

    Solution:

    7 table is

    7 × 1 = 7

    7 × 2 = 16

    7 × 3 = 25

    7 × 4 = 34

    7 × 5 = 43

    7 × 6 = 52

    7 × 7 = 61

    7 × 10 = 70

     7) 3 4 4 3 (405

      -3 4 ↓ ↓

            4 3

           - 4 3

    0

    3443 / 7 = 405
