    OPERATORS BLOCK

                     Scratch allows us to perform arithmetic and logical operations. It provides this feature
                     through Operators block. These blocks are light-green in colour.

                     ARITHMETIC OPERATORS

                     Scratch has four operators that allow you to do arithmetic calculations. These are addition,
                     subtraction, multiplication and division.

                           Operator                Meaning                              Examples

                                                                       when    clicked
                                +            Addition                  say The sum of 100 + 50 is  for 2  seconds

                                                                       say  100  + 50

                                                                       when    clicked
                                –            Subtraction               say The Difference between 100 and 50 is  for 2  seconds

                                                                       say  100  – 50

                                                                       when    clicked
                                *            Multiplication            say The Product of 10 and 20 is  for 2  seconds

                                                                       say  10  * 20

                                                                       when    clicked
                                /            Division                  say The Answer of 200/10 is  for 2  seconds

                                                                       say  200  / 10

                     COMPARISON/RELATIONAL OPERATORS

                     Scratch  has  three  operators  that  allow you  to  compare  the  relationship  between  two
                     values or variables. It will compare two numbers and decide whether it is true or false.

                     Comparison operators are used with the if... then block.

                                                                                                     Blocks in Scratch  105
