                                                TOPIC: OPERATIONS

               SUBTOPIC: Multiplication by column method and word problems


               ***Multiplication of 3-digit numbers by 2-digit.

               Step1: Arrange the numbers both multiplicand and multiplier column wise.

               Step2: First we have to multiply the multiplicand by ones digit of the multiplier, and write
               the product at the line below.

               Step3: Multiply the multiplicand by the digit at the tens of the multiplier, but place a zero
               in the ones place column, since this part of the multiplication is a number of tens.


               Step 4: Now add both the product.

               Step5: The final result of the multiplication we will get.

               Example 1: 3 2 4 x 46

               Step1:Arrange the number  columnwise









               Step2: Multiply 3 2 4 by 6 and write the result on the line below.








               Step3:Multiply 3 2 4 by 4, that is the number given in the tens place , but place a zero in
               the ones place column, since this part of the multiplication is a number of tens.
