Second
Identity property and Zero Property Multiplying
by 10 , 100 and 1000

* 3 × 1 = 3 3 × 10 = 30 3 × 100 = 300 3 × 1000 = 3000

* When multiply a number by 1 we get same number So, 1
is the multiplicative identity element

* When multiply a number by 0 the answer is 0 the Zero Property So,
The product of any number multiplied by zero is zero

* When multiply a number by 10 we add zero to the number
* When multiply a number by 100 we add two zeros to the number
* When multiply a number by 1000 we add three zeros to the number
