                     COMPARISON/RELATIONAL OPERATORS
                     These operators  allow  you  to  compare  the relationship  between  two values or
                     variables.  It  will compare  two  numbers  and  decide  whether it  is  true  or false.
     RAPID RECALL  Tick ( ) if you know this.
                     Comparison operators are used with the if... then block.

     1.  Coding blocks look like puzzle pieces that fit together to make a program.   This block checks if two values are the same. It returns
                                           =  50
     2.  Sound blocks make your projects lively with music and voices.   true if they are equal and false if they are not.
                                                       This block checks if the first number is smaller than
                                           <  50
                                                       the second.

     OPERATOR BLOCKS                                   This block checks if the first number is greater than
                                           >  50
                                                       the second.
     Operators blocks are used for mathematical calculations and logical comparisons.

     They handle things like addition, subtraction, multiplication and division, as well as   For example, let’s create the given script:
     comparing numbers and joining text.

     ARITHMETIC OPERATOR

                                               when   clicked
     Arithmetic operators  are used  to  do  mathematical  calculations  like  addition,
     subtraction, multiplication and division.   if  50 >  40  then
                                                 say  True
     +  This block adds two numbers together.  else

                                                 say  False
     -  This block subtracts one number from another.

     *  This block multiplies two numbers.

                                       superpower be and how would you use it to help others?
     /  This block divides one number by another.
