• Multiplication of 3 Digit Number by 1 Digit Number (Without carry over)

Example: 132 x 3

Step 1: Place larger number above the smaller number so that the hundreds’, tens' and ones' places are lined up. Write the multiplication sign below the top number and draw a line below the bottom number.

Step 2: Multiply the number in the ones' place of the bottom number with the number in the ones' place of the top number; 2x3 =6; write 6 in the ones place.

Step 3: Multiply the number in the ones' place of the bottom number with the number in the tens place of the top number; 3x3 =9; write 9 in the tens place.

Step 4: Multiply the number in the ones' place of the bottom number with the number in the hundreds place of the top number; 3x1 =3; write 3 in the hundreds place.

Note:

When we multiply a number by zero or zero by any number, the product is always zero.

0 x 453 = 0

781 x 0 = 0

When we multiply a number by one or one by any number, the product is always the number itself.

562 x 1 = 562

1 x 899 = 899

When we multiply a number by 10, we add 1 zero on its right side.

612 x 10 = 6120

456 x 10 = 4560

When we multiply a number by 100, we add two zero on its right side.

7 x 100 = 700

55 x 100 = 5500
