Teaching Multiplication Four Digit By Two Digit With 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.   Let us first take one example in this teaching multiplication four digit number by two digit number with regrouping to start our lesson. For Example:  4832 x 26 =   Step 1: Arrange the digits in the standard written form or vertical form as below:     Step 2; Multiply all the four digits number by the number of ones in the two digits number.      Step 3: Multiply all the four digits number by the number of tens in the two digit number.          Step 4: Add the partial product to get the answer.     We may also do in such a way such as below:       Then, you can add these two such as below:     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.
