Opposite quantities can be combined to make zero when they effectively cancel each other out. For example, if you have +5 and -5, the positive quantity of 5 and the negative quantity of 5 sum to zero. This occurs because the addition of a number and its negative counterpart results in no net value, demonstrating the principle of balance in mathematics.

If they have different magnitudes, the combined displacement is the difference between the two displacements in the direction of the larger displacement.
