Additive Inverses

This video tutorial introduces the concept of additive inverses, explaining that the additive inverse of a number is its opposite, which is equidistant from zero on a number line but on the opposite side. The additive inverse property is discussed, stating that the sum of a number and its additive inverse is zero. Several examples are provided to illustrate these concepts, followed by practice problems for viewers to solve. The video concludes with a review of the key points covered.
