n. pl. par·i·ties
1. Equality, as in amount, status, or value.

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.

7. Abbr. P Physics
a. An intrinsic symmetry property of a physical system, such as a subatomic particle, that specifies how the system would behave if the three spatial coordinates were reversed from x, y, z to -x, -y, -z.
b. A quantum number, either +1 (even) or -1 (odd), that mathematically represents this property.
8. Computers
a. The even or odd quality of the number of 1's or 0's in a binary code, often used to determine the integrity of data especially after transmission.
