The situation that describes opposite quantities that when combined would equal 0 is when a positive number is added to its negative counterpart. For example, 5 + (-5) = 0.
The situation that describes opposite quantities that when combined would equal 0 is called "additive inverse." In mathematics, if you have a number 'a' and its opposite '-a', their sum would be 0. For example, 3 + (-3) = 0 and (-5) + 5 = 0. The concept of additive inverses is fundamental in algebra and helps in solving equations and simplifying expressions.
