Question

Unary operation is one in which yields another number when performed on
$A)$two numbers
$B)$a single number
$C)$three numbers
$D)$four numbers

Answer 1

Hint: First we have to define what the terms we need to solve the problem are. since the unary operation is the form while using the operand (values, numbers, variables) and operations (expression terms, denoting terms).
Single operand only known as the unary operations will produce a new variable or value.
If two operands are called or known as binary operations.


Complete answer:
Let we need to check which of the numbers in the options will satisfy the given required question.
Since the Unary operation is one acting onto the set of another number when performed or equals (equivalent) on a single number only because of the expression that well knows $x + y = z$.
Example$2 + 3 = 5$.
Since we have seen that x, y, z are the operands (numbers or variables) will be acting to the expressions with addition and the equivalent condition in the form of unary operands.
But there are many operands like the addition, subtraction, positive terms, negative terms, and increments (increasing operand), as well as the decrement.
Hence: A unary operation is one in which yields another number when performed on a single number only.
Thus, option $B)$a single number is the correct answer.
For checking the option $A)$two numbers if two numbers will be acting on the operands will be called the binary operations not the unary operations; hence it is the wrong answer;
Now for checking $C)$three numbers while acting the three numbers operand will be called the ternary operations; similarly, $D)$four numbers are the quadratic operations while acting four numbers.
Therefore, the correct option is B

Note: In the matrix format, unitary means${A^*} = {A^{ - 1}}$, where ${A^*}$is the conjugate transpose of the matrix A and ${A^{ - 1}}$is the inverse of the matrix. For example, an identity matrix with order two.
since unary means One; binary means two; ternary means three; while acting we need the operands and the operators.
