What is the additive inverse property concerned with?

The additive inverse property is focused on the relationship between a number and its opposite, specifically how their sum results in zero. When you take any number and add its opposite (or additive inverse), the result is always zero. For example, if the number is 5, then its additive inverse is -5. The equation 5 + (-5) equals 0 exemplifies this property. This is a fundamental concept in mathematics, particularly useful when solving equations and understanding the behavior of numbers on a number line, as it establishes a balance or neutrality that allows for further calculations and manipulations within algebra and arithmetic.

The other options describe different mathematical concepts that do not pertain to additive inverses. For instance, the second option relates to the multiplicative identity property, the third involves the concept of subtraction rather than addition, and the fourth pertains to calculating the square of a number, which does not involve any inverse properties.
