Answer:
The sum of a number and its additive inverse is 0
Step-by-step explanation:
The additive inverse of a number is what you add to a number to create the sum of zero. So in other words, the additive inverse of x is another number, y, as long as the sum of x + y equals zero. The additive inverse of x is equal and opposite in sign to it (so, y = -x or vice versa).
The additive inverse of a is denoted by unary minus: −a
For real number, it reverses its sign, the opposite to a positive number is negative, and the opposite to a negative number is positive.
Zero is the additive inverse of itself.
For Example
Let us consider a number 7 .
Its additive inverse is -7
So the sum of the number and its additive inverse is
=> 7 +( -7)
=> 7 -7
=> 0
