In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
Old-fashioned doughnuts – cinnamon sugar (left), chocolate glazed (centre top) and maple glazed (right). Shape shown is typical of commercially available buttermilk donuts. The old-fashioned doughnut is a term used for a variety of cake doughnut prepared in the shape of a ring with a cracked surface and tapered edges around it. [1]
The Arrows block (U+2190–U+21FF) contains line, curve, and semicircle arrows and arrow-like operators. The math subset of this block is U+2190–U+21A7, U+21A9–U+21AE, U+21B0–U+21B1, U+21B6–U+21B7, U+21BC–U+21DB, U+21DD, U+21E4–U+21E5, U+21F4–U+21FF.
d'Alembert operator. In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: ), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator [1] ( cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French mathematician and physicist ...
APL is going to execute from right-to-left. Step 1 {of topmost APL code entered at left}) 4-5 = -1. Step 2) 3 times -1 = -3. Step 3) Take the floor or lower of 2 and -3 = -3. Step 4) Divide 1 by -3 = -0.3333333333 = final result. An operator may have function or data operands and evaluate to a dyadic or monadic function.
This is a list of all airline codes. The table lists the IATA airline designators , the ICAO airline designators and the airline call signs (telephony designator). Historical assignments are also included for completeness.

Boeing 737 Next Generation: line number 6082. Boeing P-8 Poseidon: line number 6020. Boeing 747-8: line number 1534. Boeing 767: line number 1102. Boeing 777: line number 1422. Furthermore, customer codes have never been used for Boeing airplane models launched after the termination of customer codes, namely the 787, 737 MAX and 777X .
Since the stabilizer operators of the toric code are quasilocal, acting only on spins located near each other on a two-dimensional lattice, it is not unrealistic to define the following Hamiltonian, H T C = − J ∑ v A v − J ∑ p B p , J > 0. {\displaystyle H_{\rm {TC}}=-J\sum _{v}A_{v}-J\sum _{p}B_{p},\,\,\,J>0.}
ACP-131 [1] is the controlling publication for the listing of Q codes and Z codes. It is published and revised from time to time by the Combined Communications Electronics Board (CCEB) countries: Australia, New Zealand, Canada, United Kingdom, and United States. When the meanings of the codes contained in ACP-131 are translated into various ...
In quantum mechanics, for systems where the total number of particles may not be preserved, the number operator is the observable that counts the number of particles. The following is in bra–ket notation: The number operator acts on Fock space. Let. be a Fock state, composed of single-particle states drawn from a basis of the underlying ...
