In the above example, '+' is the symbol for the operation called addition. The operand '3' is one of the inputs (quantities) followed by the addition operator, and the operand '6' is the other input necessary for the operation. The result of the operation is 9. (The number '9' is also called the sum of the augend 3 and the addend 6.)
An operation can take zero or more input values (also called "operands" or "arguments") to a well-defined output value. The number of operands is the arity of the operation. The most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication , and unary operations (i.e., operations of ...
Operands are objects upon which the operators operate. These include literal numbers and other constants as well as identifiers (names) which may represent anything from simple scalar variables to complex aggregated structures and objects, depending on the complexity and capability of the language at hand as well as usage context.
The number of arguments or operands that a function, operation, or relation takes. In logic, it refers to the number of terms that a predicate has. assertion The principle, or axiom, that (A ∧ (A → B)) → B. [20] [21] Also called pseudo modus ponens. associativity
This is called the generalized associative law. The number of possible bracketings is just the Catalan number , C n {\displaystyle C_{n}} , for n operations on n+1 values. For instance, a product of 3 operations on 4 elements may be written (ignoring permutations of the arguments), in C 3 = 5 {\displaystyle C_{3}=5} possible ways:

In logic, mathematics, and computer science, arity (/ ˈ ær ɪ t i / ⓘ) is the number of arguments or operands taken by a function, operation or relation. In mathematics, arity may also be called rank, [1] [2] but this word can have many other meanings. In logic and philosophy, arity may also be called adicity and degree.
Operation (mathematics), a calculation from zero or more input values (called operands) to an output value Arity, number of arguments or operands that the function takes; Binary operation, calculation that combines two elements of the set to produce another element of the set; Graph operations, produce new graphs from initial ones
