  1. I write the numbers one below the other, aligning the digits according to their place value. The smaller number should be written at the bottom.
  2. I multiply the bottom number by the digit in the ones position of the top number. If there are tens in the result, “regroup” them above the number in the tens position of the top number.
  3. I repeat step 2 for all digits. Do not forget to add the regrouped number (if present).

6 × 239 = ?

  1. I write the numbers one below the other, aligning the digits according to their place value. The smaller number should be written at the bottom.

I write the number 6 at the bottom since it is smaller than 239.

Multiply 6 by 239 using the column method.
  1. I multiply the bottom number by the digit in the ones position of the top number. If there are tens in the result, “regroup” them above the digit in the tens position of the top number in the multiplication.

6 × 9 = 54

Multiply 6 by 239 using the column method.
  1. I repeat step 2 for all remaining digits. Do not forget to add the regrouped number (if there is any).

6 × 3 = 18
Add the regrouped number: 18 + 5 = 23

6 × 2 = 12
Add the regrouped number: 12 + 2 = 14
