Order to show cause An order to show cause is a type of court order that requires one or more of the parties to a case to justify, explain, or prove something to the court. Definition of Order to Show Cause by Nolo Press Courts commonly use orders to show cause when the judge] needs more information before deciding whether or not to issue an order requested by one of the parties.
Order type In mathematics, especially in set theory, ordinals may be used to label the elements of any given well-ordered set (the smallest element being labeled 0, the one after that 1, the next one 2, "and so on") and to measure the "length" of the whole set by the least ordinal which is not a label for an element of the set. This "length" is called the order type of the set.
Order-embedding In mathematical order theory, an order-embedding is a special kind of monotone function, which provides a way to include one partially ordered set into another. Like Galois connections, order-embeddings constitute a notion which is strictly weaker than the concept of an order isomorphism.
Order-in-Council An Order-in-Council is a type of legislation in Commonwealth Realms. In the United Kingdom this legislation is formally made in the name of the Queen by the Privy Council (Queen-in-Council); in Canada in the name of the Governor General by the Queen's Privy Council for Canada; and in the name of the Governor-General, Lieutenant-Governor, or Governor by the Executive Council (Governor-in-Council) in other Realms, Canadian provinces, Australian states, or British Overseas Territories.
Ordered exponential The ordered exponential (also called Path-ordered exponential) is a mathematical object, defined in non-commutative algebras, which is equivalent to the exponential function of the integral in the commutative algebras. Therefore it is a function, defined by means of a function from real numbers to a real or complex associative algebra.
Ordered group In abstract algebra, an ordered group is a group G equipped with a partial order "≤" which is translation-invariant; in other words, "≤" has the property that, for all a, b, and g in G, if a ≤ b then ag ≤ bg and ga ≤ gb.
Ordered pair In mathematics, an ordered pair is a collection of two objects such that one can be distinguished as the first element and the other as the second element (the first and second elements are also known as left and right projections). A pair with no such first or second elements is sometimes referred to as an unordered pair.

Orders of approximation Orders of approximation have been used not only in science, engineering, and other quantitative disciplines to make approximations with various degrees of precision but also more generally, and more loosely, to indicate relative precision outside these disciplines in the form of "first level", "second level" and so on, "approximations". In the science and engineering disciplines approximations can be classified based on the order of magnitude of the rounding error involved.

Ordinal arithmetic In the mathematical field of set theory, there are three usual operations on ordinals: addition, multiplication, and (ordinal) exponentiation. Each can be defined in essentially two different ways: either by constructing an explicit well-ordered set which represents the operation or by using transfinite recursion.
Ordinal linguistic personification Ordinal-linguistic personification (OLP, or personification for short) is a form of synesthesia in which ordered sequences, such as ordinal numbers, days, months and letters are associated with personalities. Although this form of synesthesia was documented as early as the 1890s (; ) modern research has, until recently, paid little attention to this form (see History of synesthesia research).
Ordinal number Commonly, ordinal numbers, or ordinals for short, are numbers used to denote the position in an ordered sequence: first, second, third, fourth, etc., whereas a cardinal number says "how many there are": one, two, three, four, etc.
Ordinal scale An ordinal scale defines a total preorder of objects; the scale values themselves have a total order; names may be used like "bad", "medium", "good"; if numbers are used they are only relevant up to strictly monotonically increasing transformations (order isomorphism). See also level of measurement.
Ordinal utility Ordinal utility theory states that while the utility of a particular good and service cannot be measured using an objective scale, a consumer is capable of ranking different alternatives available. Goods are often considered in ‘bundles’ or ‘baskets’.

These approaches typically involve eschewing philosophical "theories" in favour of close attention to the details of the use of everyday, "ordinary" language.

Ore condition In mathematics, the Ore condition in ring theory is a condition introduced by Øystein Ore, in connection with the question of extending beyond commutative rings the construction of a field of fractions, or more general localization of a ring. The left Ore condition reads that for a ring R, and any pair a, b of non-zero elements, the sets aR and bR should intersect in more than the element 0.
Ore dressing Ore dressing is one of the principal processes in the work of mining. When the miner hoists his ore to the surface, the contained metal may be either in the native uncombined state, as, for example, native gold, native silver, native copper, or combined with other substances forming minerals of more or less complex composition, as, for example, telluride of gold, sulphide of silver, or sulphide of copper.
Ore grade Ore grade is a measure that describes the concentration of a valuable natural material (such as metals or minerals) in its surrounding ore. Ore grade is used to assess the economic feasibility of a mining operation: the cost of extracting a natural material from its ore is directly related to its concentration, and the cost of extraction must be less than the market value of the material being mined for the operation to be economically feasible.

The first few Ore harmonic numbers are 1, 6, 28, 140, 270, 496, 672, 1638, … .
Ore's theorem Ore's theorem is a result in graph theory due to Øystein Ore (1960). It gives a sufficient condition for a graph to contain a path that starts and ends at the same vertex and includes each vertex exactly once.
Ore-bulk-oil carrier As their name suggests, ore-bulk-oil carriers, also known as combination carriers, are designed to be capable of carrying wet or dry cargoes. The idea is to reduce the number of empty ("ballast") voyages, in which large ships only carry a cargo one way and return empty for another.
