How To Multiply Three Digit Numbers With 100

Multiplication is the process of repeated addition. The result of multiplication is called product. For example: 3 x 5 = 5 + 5 +5 = 15 Multiplication is a commutative operation, that is, changing the order of the numbers does not affect the product. For example, 6 x 3 = 18 is the same with       3 x 6 = 18.   The principle use in this “How To Multiply Three Digit Numbers With 100″ can be use at  multiplication two digit numbers with 100 and four digit numbers with 100 too.   For example: 725 x 100   1. Multiply 725 by 1 hundreds in the vertical form.     Encourage the kids to say out orally:       5 x 1 hundreds =     5 hundreds   20 x 1 hundreds =   20 hundreds 700 x 1  hundreds = 700 hundreds     2. Add 5 hundreds, 20 hundreds and 700 hundreds.     3. Since it is multiply by 100, place the two zeros (00) to the right after the product.     **  Points to note:   Tens has one zero (0) Hundreds had two zeros (00) Thousands has three zeros (000)    4. Multiplication any four digit numbers with 10, two digit numbers with 100000 is the same way as multiply three digit numbers with 100.   In mathematics, multiplication is one of four main operations in elementary arithmetic, and most people learn basic multiplication algorithms in elementary school. The inverse of multiplication is division.
