Operations of reciprocatioп апd inversion of complex physical values

The operations of reciprocation $V^{-1}$ and inverse $V^'$ of indefinite complex physical quantities are defined and investigated. It is noted that the operations of additions, inverse (harmonic) addition $V_{1}∙V_{2} =(V_{1}^' + V_{2}^')^'$, and inversion of indefinite complex quantities $V_{1}$ and $V_{2}$ are generalizations of the basic operations of Boolean algebra. At the end of the article, we examine the question of whether the inversion operation can actually (physically) be carried out for any complex (and in particular, real) physical quantities.
