DAV Class 4 Maths Chapter 3 Worksheet 2 Notes
Properties Of Multiplication
If two numbers are multiplied in either order, the product remains the same,
e.g. 5 × 3 = 15
3 × 5 = 15
.’. 5 × 3 = 3 × 5
If 3-digit are there i.e. 3, 2, 5 we can multiply it in six different orders.
1st order : 3 × 2 × 5 = 30
2nd order : 2 × 3 × 5 = 30
3rd order : 5 × 3 × 2 = 30
4th order : 3 × 5 × 2 = 30
5th order : 2 × 5 × 3 = 30
6th order : 5 × 2 × 3 = 30
So if the three numbers are multiplied in any order, the product remains the same.
Multiplication of number by 1:
The product of a number and 1 is the number itself.
e.g. 19 × 1 = 19
Multiplication of a number by zero:
The product of any number and zero is zero,
e.g. 7 × 0 = 0
