Question $2$

A binary operation is a mathematical operation performed on two elements to derive a element $($two inputs, one output$).$

An unary operation is a mathematical operation performed on one elements to derive another element $($one input, one output$).$

For example operation of multiplication is a binary operation: it takes two numbers and result it gives one number $($let$\text{'}$s say: two numbers $3$ and $5$ result in $3^{**}5=15)$

Operation of taking an absolute value is not a binary operation since it "operates" only o number $($you take absolute value of one number$).$ It is an example of unary operation.

Determine which of the following operations are binary, unary or neither.
