Multiplication is one of the basic and important arithmetic operation used in different branches of mathematics. Multiplication is denoted by a cross sign ×. Multiplication of two numbers is like adding one them as many times as the other number. In multiplication the order of the numbers doesn’t change the answer.

Example 1: There are 32 students in a class. If there are 4 such classes, how many are the total number of students?
Solution: Number of students in each class = 32.
Number of classes = 4.
Total number of students = 32 x 4.
Here for the multiplication 4 is multiplied to the one’s place 2 x 4 = 8.
Now the 4 is multiplied to the ten’s place 3 x 4 = 12.
Now placing the numbers next to each other. Hence 32 x 4 = 128 Total number of students = 128.
