Learning Simple Multiplication Three Digit Numbers With Two Digit Number Without Regrouping

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.   This Learning Simple Multiplication Three Digit Numbers With Two Digit Number Without Regrouping can be used for teaching three digit or four digit numbers without regrouping too. Example: 214 x 12    2 1 4 x   1 2           1. Multiply 214 x 2     2 1 4   x     2         8 (4 ones x 2 = 8 ones)     2 0 (1 tens x 2 = 2 tens)   4 0 0 (2 hundreds x 2 = 4 hundreds)   4 2 8     Calculation:     Multiply 214 by 1 tens     2 1 4   x     1 Tens       4 Tens     1 0 Tens   2 0 0 Tens   2 1 4 Tens = 2 1 4 0   Calculation:     3. Add the two products       4 2 8   x 2 1 4 0     2 5 6 8 (answer)     Shortcuts       Simplify     So, let the kids consider to have   4 x 20 4 x 2 tens = 8 tens or 80   30 x 20 30 x 2 tens = 60 tens or 600   200 x 20 200 x 2 tens = 400 tens or 4000   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.
