Inverse property of addition:
This property states that when you add any real number with its additive inverse then the result is zero.
Let x be a real number.
The additive inverse of x is -x

Example:
Let us consider a real number 5
The additive inverse of 5 is -5
So, as per inverse property of addition,

Similarly, let us consider a real number 1.33
The additive inverse of 1.33 is -1.33
So, as per inverse property of addition,

Therefore, the sum of any real number with its inverse results in zero.
