# Multiplying by 11

Use the following steps to multiply by 11:

• Write down the last digit of the number you are multiplying by 11.
• Add the last digit to the digit on its left. Write down the last digit of the sum and carry if necessary.
• Move one digit to the left.
• Add that digit to the digit on its left. Write (to the left) and carry.
• Continue the process of moving to the left and adding until there are no more digits.

Example:

23 Ã— 11 =

 Write the last digit: 3 3 Add 3 and 2. 3 + 2 = 5 53 Move to the 2. Since there are no more numbers to the left of the 2 and there is no carry from the previous sum, write down 2. 253

Therefore, 23 Ã— 11 = 253.

Example:

846 Ã— 11 =

 Write the last number: 6 6 Add 6 and 4. 6 + 4 = 10. 06 (carry 1) Move to the 4. Add 4 and 8 and the carry. 4 + 8 + 1 = 13 306 (carry 1) Move to the 8. Since 8 is the last number, just add the carry. 8 + 1 = 9 9306

Therefore, 846 Ã— 11 = 9306.
