    Answer for Question 1

    A unary operation is an operation with only one operand, i.e. an operation with a single input, or in other words, a function of one variable.

    Examples:
    x++
    ++y
    --z

    A binary operation is a calculation involving two operands, in other words, an operation whose arity is two.

    Examples:
    x + y
    128 * 978
