Quanta {quantum number}|, such as electric charge, can be additive integers {additive quantum number}. Antiparticles have negative of additive-particle quanta. Mass is not additive. Quanta, such as parity and g-parity, can be multiplicative {multiplicative quantum number}, based on nth roots of unity. Fermions have -1 parity. Bosons have +1 parity. Two interacting fermions make boson: -1 * -1 = +1. Two interacting bosons make boson: +1 * +1 = +1. Three quarks make hadron, with parity -1: -1 * -1 * -1 = -1.
