**par·i·ties**

**1.**Equality, as in amount, status, or value.

**2.**Functional equivalence, as in the weaponry or military strength of adversaries: "A problem that has troubled the U.S.-Soviet relationship from the beginning has been the issue of parity" (Charles William Maynes).

**3.**The equivalent in value of a sum of money expressed in terms of a different currency at a fixed official rate of exchange.

**4.**Equality of prices of goods or securities in two different markets.

**5.**A level for farm-product prices maintained by governmental support and intended to give farmers the same purchasing power they had during a chosen base period.

**even parity**) or changes in sign (

**odd parity**)

**b.**a quantum number describing this property, equal to +1 for even parity systems and –1 for odd parity systems. Symbol:
