Which situation describes opposite quantities that when combined would equal 0?
The situation that describes opposite quantities that when combined would equal 0 is when the quantities have the same magnitude but opposite signs. For example, if you have +5 and -5, when you combine them, they would equal 0.

The situation that describes opposite quantities that when combined would equal 0 is known as the concept of "additive inverses." In mathematics, the additive inverse of a number is the number that when added to the original number gives a sum of zero. For example, the opposite quantity or the additive inverse of +5 is -5 because 5 + (-5) equals 0. Similarly, the opposite quantity or the additive inverse of -3 is +3 because -3 + 3 also equals 0. In general, the opposite quantity of any number 'a' is represented as '-a'. When two opposite quantities are combined, their sum is always zero.
The situation that describes opposite quantities that when combined would equal 0 is called "additive inverse." In mathematics, any number added to its additive inverse will result in 0.
To find the additive inverse of a given number, you simply change the sign of the number. For example, the additive inverse of 5 is -5, and the additive inverse of -8 is 8. When you add these pairs together, you get 5 + (-5) = 0 and -8 + 8 = 0, respectively.
So, any pair of opposite numbers, where one is positive and the other is negative, will sum to 0 when added together.
