Multiplying Numbers | Elementary

Multiplication is an operation that makes it possible to repeat a number or a quantity a certain number of times.

The multiplication statement 5 × 7 means adding a group of 7 five times.

5 × 7 = 35

The multiplication statement 4 × 244 means adding a group of 244 four times.

244 + 244 + 244 + 244 = 976

4 × 244 = 976

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 = ?

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.
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
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

6 × 239 = 1 434

Multiplication is an operation that makes it possible to repeat a number or a quantity of objects several times.

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 digit in the ones position of the bottom number by each of the digits in the top number.

3. I write 0 in the ones place under the result.

4. I multiply the number in the tens position of the bottom number by each of the digits in the top number.

5. I add the 2 results written below the line to get the final product.

35 × 162 = ?

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 35 at the bottom since it is smaller than 162.
I multiply the digit in the ones place of the bottom number by each of the digits in the top number.
I write 0 in the ones place under the result.
I multiply the digit in the tens position of the number below by each of the digits in the number above.
I add the two results written below the line to get the final product.

162 × 35 = 5 670
