Lesson 6: Multiply Whole Numbers With Zeros

Property

To multiply a 3-digit number containing a zero by a 2-digit number, use the standard algorithm.
First, find the partial product by multiplying the top number by the ones digit of the bottom number.
Then, find the second partial product by multiplying the top number by the tens digit, placing a zero in the ones place.
Finally, add the two partial products to find the final product.

Examples

• Find the product of $309 \times 42$:

• Find the product of $704 \times 56$:

• Find the product of $430 \times 56$:
