The statement given is:
Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.
So, the value of 
must be 0 because on adding to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
