<strong>Additive inverse</strong><strong>Multiplicative inverse</strong>An additive inverse is a number that, when added to the original number, it results in 0. Multiplied the original number by the inverse of the number, the result is always 1. The additive inverse of a real number n is -n. The multiplicative inverse of a real number n, except 0 is \(\frac{1}{n}.\) It is the negative of the original number. It is the reciprocal of the original number. When a number and its additive inverse are added, the sum is 0. When a number and its multiplicative inverse are multiplied, the<a>product</a>is 1. The additive inverse of 0 is 0. 0 has no multiplicative inverse.<h3>Explore Our Programs</h3>
