                  Let us learn more about Scratch.

                       OPERATORS

                  These blocks are colour-coded as light-green. Operators Blocks are used to do arithmetic and
                  logical calculations. Blocks in the Operators category are oval and hexagon in shape.

                  There are a total of 18 operator blocks, out of which, 7 blocks are Boolean blocks and the rest
                  11 blocks are reporter blocks. Boolean blocks are hexagonal blocks that gives only Boolean

                  values (‘true’ or ‘false’), whereas, Reporter blocks are the blocks that returns a value that can
                  be in numbers to strings.

                  Arithmetic Operators

                  Scratch has four operators that allow you to do arithmetic calculations. These are addition,
                  subtraction, multiplication and division. Look at the code to use addition block.

                                                             Addition

                  Similarly, you can use the other blocks to perform subtraction                 , multiplication

                  and division          .
