                                                                     say 50 is less than 100






                                                                   when     clicked
                          = 50           Equals to                 if     50  = 50     then
                                                                     say Both the numbers are equal






                 LOGICAL OPERATORS
                 Logical operators are used to combine two or more conditions. Logical operators are

                 used when we want to test more than one condition and make a decision. It produces the
                 results by considering if the conditions entered are true or false. In Scratch, there are three
                 logical operators: ‘and’, ‘or’, and ‘not’.




                       Operator                Meaning                              Examples



                                         Logical and               when    clicked


                          and            The result is true if     if     100  > 50  and    100  > 60   then
                                         both the conditions         say 100 is greater than 50 and 60
                                         are true.



                                         Logical or                when    clicked

                           or            The result is             if     100  > 50    or    100  > 200   then
                                         true, if one of the         say 100 is either greater than 50 or 200
                                         statements is true.


                                         Logical not

                                         Reverses the              when    clicked

                        not              condition, i.e., it’s     if    not     50  > 100   then
                                         false if the condition

                                         is true and                 say Reverses the condition
                                         vice-versa.
