Algorithm for Multiplication and Division of a Three-Digit Number

To perform multiplication and division with a three-digit number, we'll provide step-by-step instructions for both operations. Let's start with multiplication.

Multiplication Algorithm

To multiply a three-digit number by another number, follow these steps:

1. Write down the three-digit number and the other number one below the other, aligning them on the right. 2. Multiply the ones digit of the three-digit number by the other number, and write the result below the line. 3. Multiply the tens digit of the three-digit number by the other number, and write the result one position to the left of the previous result. 4. Multiply the hundreds digit of the three-digit number by the other number, and write the result two positions to the left of the previous result. 5. Add up the three results to get the final product.

Let's illustrate this algorithm with an example:

Example: Multiplying 135 by 6

   135
x   6
-----
   810   (ones digit: 5 x 6)
  540    (tens digit: 3 x 6)
+ 900    (hundreds digit: 1 x 6)
------
  810    (final product: sum of the three results)

Division Algorithm

To divide a three-digit number by another number, follow these steps:

1. Write down the three-digit number and the other number one below the other, aligning them on the left. 2. Divide the leftmost digit of the three-digit number by the other number, and write the quotient above the line. 3. Multiply the quotient by the other number, and write the result below the line. 4. Subtract the result from the leftmost digit of the three-digit number, and write the difference below the line. 5. Bring down the next digit of the three-digit number and repeat steps 2-4 until all digits have been processed. 6. The final result is the quotient obtained from the division.

Let's illustrate this algorithm with an example:

Example: Dividing 270 by 45

   270
÷  45
-----
    6   (leftmost digit: 270 ÷ 45 = 6)
  -----
   270   (quotient: 6 x 45 = 270)
- 270   (difference: 270 - 270 = 0)
------
     0   (final result: quotient obtained from the division)

Please note that the algorithm for division may vary slightly depending on the specific division method used (e.g., long division, short division). The above algorithm provides a general approach for dividing a three-digit number by another number.

I hope this explanation helps! Let me know if you have any further questions.
