    • 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
