0. By the definition of "additive inverse", the sum of ANY number and its additive inverse must be 0.


Why is the sum of a rational number and its opposite always epual to zero?

Because that is how its additive inverse is defined!


When a number is added to its additive inverse what is the sum equal to?

Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0) Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0)


What is the additive inverse of eighteen?

The additive inverse of 18 is -18. The additive inverse of any number is the opposite of that number, such that the sum of the original number and the additive inverse is zero.


What is the additive inverse of .5?

The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).


What is the additive inverse of 41?

The additive inverse of 41 is -41. An additive inverse is the number that will make the sum equal zero.


When the number is added to its additive inverse what is the sum equal to?

It is zero, by definition of additive inverse!


What is the sum of any rational number and its opposite?

If we define "opposite" as the additive inverse, the sum is zero.


Is the sum of two rational numbers sometimes 0?

Yes. For example: * 0 + 0 = 0 * 1/1 + (-1/1) = 0 * 1/2 + 1/3 is not equal to zero. If the second rational number is the additive inverse of the first, then yes the sum of two rational numbers can be zero. The additive inverse is that number when added to another number gives the result 0, and is denoted as the negative of the first number; the additive inverse of the number a is denoted by -(a) and is such that a + -(a) = 0. eg the additive inverse of 1/2 is -(1/2) giving 1/2 + -(1/2) = 0.


What does mean additive inverses?

The additive inverse of a number is the negative of that number. Given one number, its additive inverse is the number that needs to be added to it so that the sum is zero. Thus: The additive inverse of 2.5 is -2.5 The additive inverse of -7.998 is 7.998
