The additive inverse of a number is the value that, when added to the original number, results in zero. In other words, it is the negative of the original number. For a number "a," its additive inverse is "-a," such that "a + (-a) = 0." For example, the additive inverse of 7 is -7, because 7 + (-7) = 0
. This concept is applicable to real numbers, complex numbers, and algebraic expressions, and it is closely related to the operation of addition and the concept of the additive identity, which is zero
