Topic : Operations on Large Numbers

Multiplication of large numbers : We know that the multiplication of a number by a 2- digit or 3- digit number. In the same way , we multiply with large numbers .
For example : Multiply 3245 by 243 .
Solution : 243 = 200 + 40 + 3
3245 × 243 = 3245 × ( 200 + 40 + 3 )
= 3245 × 200 + 3245 × 40 + 3245 × 3
= 649000 + 129800 + 9735
= 788535
