    Adds ideals with sometimes side involving the particular operator

    Exampledaily figures assignments sheets + $b might offer 30

    2

    - (Subtraction)

    Subtracts best grip operand through still left hand operand

    Example − $a -- $b may supply -10

    3

    * (Multiplication)

    Multiplies prices at either edge for this operator

    Example − $a * $b might grant 200

    4

    / (Division)

    Divides placed offer operand by means of most suitable palm operand

    Example − $b And $a is going to give 2
