To multiply a multi-digit number by a one-digit number, multiply

each digit in the multi-digit number by the one-digit number.

**Step 1:** Write the second number under the first number so that the corresponding places are lined up.

**Step 2:** Multiply the bottom number by the ones digit in the top number

(9 × 8 = 72). Since 72 has two digits, both digits won't fit in the ones place. So, write the 2 in the ones place of the

product, and carry the 7 to the

tens column.

**Step 3:** Multiply the bottom number by the tens digit in the top number

(9 × 8 = 72). Then, add the 7 that was carried to the tens column in the previous step (72 + 7 = 79).

Since 79 has two digits, both digits won't fit in the tens place. So, write the 9 in the tens place of the

product, and carry the 7 to the

hundreds column.

**Step 4:** Multiply the bottom number by the hundreds digit in the top number (9 × 1 = 9). Then, add the 7 that was carried to the hundreds column in the previous step (9 + 7 = 16). Write the 6 in the hundreds place and the 1 in the thousands place of the sum.
