Quaternions and rules for operations on them were invented by Irish mathematician Sir William Rowan Hamilton in 1843.
The introduction of a special reference frame or coordinate system establishes a correspondence between vectors and sets of numbers representing the components of vectors in that frame, and it induces definite rules of operation on these sets of numbers that follow from the rules for operations on the line segments.
The certificate of airworthiness was issued by the national authorities for aircraft that conformed to a type design approved under a type certificate, and with the applicable national rules for operations and environmental protection.
The FAA's rules for operation and certification for small UAS (summarized here) will go into effect August 29, 2016, establishing routine civil operations and safety.

However, a well-functioning regional market will require implementing necessary reforms in order to meet global market standards, pursuing policies that promote the harmonization of national regulations and technical rules for operation of power systems, and removing subsidies or any other barriers that can impede competition and the smooth physical flow of power.

During the implementation process, other problems arose, and new topics were included in the management plan, such as real estate regulations, garbage and sewage disposal, the regulation of domestic animals, rules for summer operations, and conduct adjustment terms.
For instance, given the expression 'a b + x y,' the rules of algebra license swapping the two algebraic sub-expressions, 'x y' and 'a b,' to get the new expression 'x y + a b.' By contrast, one cannot swap the two adjacent variables 'b' and 'x' to get 'a x + b y.' This manipulation violates the precedence rules for arithmetic operations.
