## What is the algebraic concept of inverse? |

“Inverses” in algebra are operations (or numbers) that “undo” each other. For example, if one multiplies 4 times its inverse, or 1/4, the solution is 1; thus, the rule for multiplicative inverse for *x* (with *x ≠* 0) is 1/*x*, as in *x*(1/*x*) = 1. In addition, if you add -4 to 4, you get zero (0); thus, the additive inverse of *x* is -*x*, as in *x* + (-*x*) = 0.
